Structural Behavior of Precast Lightweight Foam Concrete Sandwich Panel with Double Shear Truss Connectors under Flexural Load

Experimental Study on Flexural Behavior of Precast Concrete Shear Walls with Vertical Joint

Connections for Precast Concrete Load-bearing Shear Wall Panels

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection '~md the overall integrity of the structure. This paper presents the results of a four-year research program conducted to i...

Designing a prefabricated sandwich composite roofing system Made up of resisting facings and light-weight concrete core with truss-shaped connectors

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...

Foam Concrete Precast Elements in Composite Concrete-GFRP Plate Girders

This paper is focused on using foam concrete as structural element in polymer-concrete composite plate girders. Trial mixes of foam concrete and different proportions of foam agent were considered to obtain the suitable mix that can be used as structural element in composite girders system. Details of the experimental investigations on foam concrete precast slabs and polymer-concrete composite ...

Bending behavior of lightweight sandwich-walled shells with pyramidal truss cores

A study on the bending response of a composite curved panel with pyramidal metallic truss cores suitable for functional applications is presented using a combination of analytical modeling, three-point bending experiments and finite element (FE) based simulations. The aluminum pyramidal cores were constructed using an interlocking method before curing with composite face sheets to fabricate the...
