Experimental Research On Behavior Of Concrete Beam With Encased Vierendeel Steel Truss

As the development of architectural structure, the steel-concrete composite structures are more and more popular used and it becomes the fifth biggest structure as well as the common steel concrete structure,masonry structure, steel structure and timber structure.Steel-concrete structure can make full use of the concrete's capacity of resisting compress and the capacity of steel of resisting tensile force,the utility of steel can reduce the section of concrete,and the effective use of concrete can strengthen the capacity of resisting of fire for steel structure.In addition composite structure can improve the capacity of shock resistance.In this article,it studies the limited load-carrying capacity and distortion characteristics of concrete beam with encased vierendeel steel truss with the different space between slabs.It will prove the Assumption of Plane Section and find the plastic hinge regions.Then it will be compared to the limited load-carrying capacity of common steel-concrete,to get the calculate formula of the limited load-carrying capacity initially.At the same time it will be compared to other steel reinforced concrete and steel-concrete composite.Then it will supply some referration for experiments and the applications of project.
