Experimental Study On Cast-in-place Light Composite Wall Vertical Bearing Capacity

The cast- in-place light composite wall is utilized by light steel keel and fiber cement pressure plate to support formwork, pouring the mixed material composed of a large number of tail slag and other industrial waste and compound additive etc. inside, forming a composite wall. In recent years, the steel residential structure in C hina has been well promoted and applied, the cast- in-place light composite wall has made a larger development. However, the relevant rules and norms of the cast- in-place light composite wall are not perfect, generally reference to overseas relevant standards, not entirely suitable for our country. At the same time, as a self- load-bearing wall, domestic and foreign research generally consider light steel keel bearing capacity, less studies on plate and core auxiliary effect on light steel keel vertical bearing capacity, further research on this paper, hope to provide reference for the relevant design.In this paper, the experimental research under the vertical load on 3 forms of wall through separate light steel dragon skeleton, with fiber cement pressure plate on both sides composite wall, with fiber cement pressure plate on both sides and internal pouring foam concrete core composite wall, receives 3- group test walls ultimate bearing capacity, failure mode and deformation, analysis of the fiber cement pressure plate and foam concrete core material for light steel keel to withstand the vertical load bearing capacity effect is very obvious, with fiber cement pressure plate on both sides composite wall can average increase the vertical keel vertical bearing capacity of about 14.3 percent, with fiber cement pressure plate on both sides and internal pouring foam concrete core composite wall can average increase the vertical keel vertical bearing capacity of about 38.3 percent. It can be seen that under the constraint effect of fiber cement pressure plate and foam concrete core, the vertical keel vertical bearing capacity has been significantly improved. At the same time, 3- group test walls finite element analysis is carried out using ANSYS finite element analysis software. Experimental research and ANSYS finite element analysis of cast- in-place light composite wall vertical bearing capacity in this article has some theoretical significance and application value on promotion and application of cast- in-place light composite wall and this architecture in China, at the same time, on the basis, put forward to some certain recommendations for future researchers engaged in the kind of analysis study.
