High tensile strength of structural steel and the high compressive strength of concrete High durability of normal reinforced concrete decks due to restrictive crack width limitation. In comparison with steel bridges composite bridges have a better behaviour with regard to freezing in winter. Because the low dead weight of the composite bridges deck is, composite bridges have advantages with regard to the foundation and settlements of supports. Due to innovative erection methods composite bridges are often used for bridges over passing existent railways or highways without any restrictions for the traffic. Where existing freeways with two lanes are widened the short erection time of composite bridges avoids longer restrictions for traffic.

 

There are a number of ways of providing a shear connection between the steel/composite girders and the deck slab, but by far the most common is the headed stud connector. This is a headed dowel that is welded to the top flange using a special semi-automatic welding tool that supplies an electrical pulse sufficient to fuse the end of the dowel to the flange. In Hanson Heavy industry, the technology is available to be able to weld studs onsite, regardless of weather conditions. However, most studs are welded in the fabrication shop during the fabrication of the beams, which is the most cost-effective option and avoids the risk of damage to protective coatings. There are other forms of shear connectors, such as welding steel bars with hoops, perforated plates, welded T-shaped plates and short lengths of channel. Although these connectors provide a higher longitudinal shear resistance per unit, as demonstrated by testing in plates and T_shaped plates, they each have to be welded manually and consequently are more expensive under following.

Framed abutments are usually built with H-piles or reinforced concrete piles, with the piles inside sleeves, thus avoiding earth pressures on the piles as the bridge expands. A typical arrangement is shown in figure, with a normal earth slope in front and a reinforced earth retaining wall. Depending on soil conditions, one or two piles are provided for each main girder in multi-girder bridges; for a ladder deck bridge of the same overall width, a similar total would be provided, though they might be concentrated around the positions of the main girders. Framed abutments are also built with reinforced concrete abutment walls on strip footings, although that form of construction is not discussed in this guide. In principle, any type of bearing pile, including steel H-piles, can be driven into the ground and the endscreen wall cast around the tops of the piles. In practice, only a small number of bridges have been built with H-piles. Where construction has used H-piles, they have usually been encased in a pile cap just below the bottom of the main girders. Plates for temporary bearings are set into the pile cap and the end-screen wall is completed later, after the deck steelwork has been erected and the deck slab cast. With fully integral construction, bracing for the construction condition may be arranged within the wall (and will be cast in) or just in front of it (but then there must then be access for maintenance).

Why Specify A Composite Bridge

Most short span bridges  US (and in most countries around the world) with spans up to 30 m have been built in concrete, typically comprising precast concrete beams and reinforced concrete decks. However, a well-designed steel-concrete composite bridge comprising steel girders and reinforced concrete decks will also provide an economical and sustainable solution. Figure demonstrates the potential spans to superstructure type for both steel-concrete composite and concrete bridges, even though longer spans may be possible for some of the options shown. Although steel bridges are commonly used in medium spans (between 30m to 80m) and especially for long spans (greater than 80 m), the guidance and design philosophy outlined in this section provides the designer with the tools to design a cost-effective steel-concrete composite bridge, whether it is a short, medium or long span structure. Framed abutments are usually built with H-piles or reinforced concrete piles, with the piles inside sleeves, thus avoiding earth pressures on the piles as the bridge expands and contracts. A typical arrangement is shown in figure, with a normal earth slope in front and in figure with a reinforced earth retaining wall. Depending on soil conditions, one or two piles are provided for each main girder in multi-girder bridges; for a ladder deck bridge of the same overall width, a similar total would be provided, though they might be concentrated around the positions of the main girders. Framed abutments are also built with reinforced concrete abutment walls on strip footings, although that form of construction is not discussed in this guide.

Bridge Design | Acerts

In late 2006, a three-span private test bridge was designed originally with a conventional double hollow core deck on pier cross-head beams. The 17m span is within the optimum range for hollow core units. However, by changing the super structure to a steel/concrete composite ladder deck system, taking advantage of continuity over the three spans and eliminating the expensive cross-head girders, a more cost-effective solution was obtained. The ladder deck system consisted of two main girders at 9m centres, with 18 intermediate cross girders at 3m centres. Initially, the chosen decking system for the composite bridge was a partial depth precast concrete decking; however, due to manufacturing issues which affected the project delivery date, a steel decking option was considered as permanent formwork. Steel decking with a total of 330 mm in concrete topping to minimise formwork requirements. The decking was only used as permanent formwork and was not considered to act compositely with the concrete. The cost comparison between the hollow core decks, partial depth precast decking and the use of the steel decking option. It is clear that the composite steel bridge options were more cost effective than the conventional hollow core concrete decking, once the total cost of the project was considered. The super structure costs of the three options are comparable, with most of the cost savings attributed to the substructure, especially with the removal of the pier cross head beam and the replacement of the abutments with a concrete segmental retaining wall. An interesting fact is that the steel decking option provided greater cost savings than the partial depth precast concrete decking option, with a savings of  $37,492 between the two composite steel bridges options. The steel-concrete composite bridge provided a total of $76,295 savings in comparison to the concrete double hollow core bridge. Further savings were achieved by removing the abutment and replacing it with a concrete segmental retaining wall with a fill behind the wall. The fill had driven timber piles to support the crane bearing pads during construction. This bridge was for a private client and had a specified design life of 50 years, whereas the Bridge manual requires 100 years. Appearance was not a concern; therefore unprotected steel was used with a design allowance for loss of steel from corrosion in accordance with El Sarraf and Clifton (2011). However, the cost of a coatings system to give a period of 35 years prior to its first maintenance would have been $28,000, giving a net cost saving for a coated bridge of $48,295 for the steel decking composite steel bridge option. It should be noted that there are limitations on the use of steel decking from a durability perspective. However, as this option was used as a permanent formwork only, this was not considered to be an issue. Certain corrosion protection measures can be undertaken to increase the design life of the steel decking as required. The fact that this was a privately funded project allowed the innovative use of steel decking, as a permanent formwork. For a publicly funded project, the guidance given in the NZTA contract documents on the use of steel decking should be followed for each project.

At A Cert our expertly is to embed real stones work with mortar joints that were neither too shallow nor too deep, while being careful to avoid cement stains on the rock faces. He also needed to find a way to structurally connect the walls to the footings and to the other walls-while artfully hiding the joints between them. We have lots of practiced on Tilt-up construction. As with any new building technique, there were many hurdles to cross to get a working system. Tilt-up construction is hardly new, but the panels are usually faced with coarse, decorative gravel that is simply raked into the forms before the pour. Stone masonry is the stuff of castles and cathedrals and of houses that have been around for centuries, or will be. It is the Gold Standard of the construction world.  Keep in mind that the ground is part of the formwork, so it must be perfectly flat, but you don’t need a concrete slab to work. Level the site as much as possible, then stake down the perimeter forms and level them at the corners. Next, rake the ground smooth inside, adding or removing dirt as necessary. Make a screed that fits inside the forms to check for level, and spread a thin layer of sand over the site to make a good surface to work from.

We believe a building project, regardless of its production method, is an ambitious undertaking. The sheer number of individuals, teams, materials, products, systems, communication, and finances that are implicit in the finished building is difficult to fathom. The process of a building coming into being can be likened to an orchestra, where all the players and their instruments of practice are important to the success of the intended finished product. The lifecycle of a facility refers to its conception, design, construction, and post construction facilities management. During each phase of the lifecycle of a building, different players take on a different role, are more important or less, depending on the time in the performance. Each building undertaking has a number of key principles that it must answer to. Although not all of the issues may be critical for a given project, generally, a building must respond to the following principles of construction and their effect on productivity:

  • Cost: capital and operational investment
  • Labor: skilled and unskilled human workforce
  • Time: schedule or duration of the project
  • Scope: extent or breadth of the project
  • Quality: design and construction excellence
  • Risk: exposure to potential financial loss

The owner team’s priorities regarding the project will determine how much emphasis is placed on cost, schedule, and scope. Buildings are expensive and owner teams are rarely unrestricted in their ability to fund them. In addition, most projects are on a limited schedule to allow for occupation by a certain date. Related to cost, schedule, and scope are the principles of quality and risk.

Commercial Building Foundation Piers

When it comes to commercial foundation repair, Acerts has the necessary solutions to keep your structure stable under tight budget. If your building has a shifting or sinking foundation, you may need to invest in commercial building foundation piers. Foundation piers are an excellent solution for most failing foundations. They are able to effectively lift and stabilize the foundation to keep your building from developing other problems. Atlas Piers provides a selection of different foundation pier services for your commercial foundation repair needs.Commercial Building Foundation Piers needed when the soil beneath your foundation erodes or shrinks due to drought conditions, voids may form under the foundation. This lack of support beneath the foundation can cause it to sink or settle. This problem might also be the result of too much hydrostatic pressure in the soil around the foundation, pushing on it and making it crack or shift. Fortunately, a settling foundation can usually be fixed or prevented with the installation of foundation repair products like helical piers or steel push piers. Foundation piers are important to your commercial buildings because they can help to prevent and repair most common foundation problems. If your foundation fails, it will cause other problems throughout the structure, such as: bowing walls, leaning walls, cracks in the walls and floors, sticking windows, sticking doors, and sloped or uneven floors. These are annoying issues that can result in expensive repairs. They can also be hazardous to you and anyone else that frequents the building. By investing in commercial building foundation piers for your business, you can save money in the long run and keep your building safe.
