Construction Technique And Finite-element Analysis Of CFERP Structures

As one of the important factors of green struction, green construction material plays an important in the sustainable development of construction industry.New safety construction material—rapid wall(concrete-filled fiber-reinforced plasterboard ) have many advantages when applied in buildings which is the excellent succedaneum of the conventional constrction material—clay soil brick.At present, research on concrete-filled fiber-reinforced plasterboard(CFFRP) is still preliminary.Due to the advantages in structure especially in residential construction, some demestic departments plan to introduce the material fiber- reinforced plasterboard (rapid wall).However,in Australia no seismic behavior is in consideration.So the research on the seismic behavior of CFFRP has important theoretical significance and engineering value.First, construction technique and some construction problems were discussed in this dissertation.Following, based on the model experiment on seismic behavior of CFFRP, a command stream is edited with the ANSYS Parametric Design Language (APDL), and the nonlinear finite element analysis of the structure on the seismic behavior and model walls under horizontal-low-cyclic loading with constant vertical loading is completed. The calculated results are much coincided with the tested results.Finally, an analysis of dynamic character and elastic earthquake response was made with FEA software,Sap2000. The results of analysis indicated that CFFRP has enough stiffness and sideways resistance capacity, so it can apply in 7 degree seismic zone.
