Experimental Research And Finite-element Analysis On The Seismic Behavior Of Joints Of T-type Builded With Concrete-filled Fiber-reinforced Plasterboard

As one of the important factors of green struction,green construction materialplays an important in the sustainable development of construction industry.New safetyconstruction material—rapid wall( fiber-reinforced plasterboard ) have manyadvantages when applied in buildings and concrete-filled fiber-reinforced plasterboard(CFFRP) is the excellent succedaneum of the conventional constrction material—claysoil brick.At present, research on CFFRP is still preliminary.Due to the advantages instructure especially in residential construction, some demestic departments plan tointroduce the material fiber-reinforced plasterboard (rapid wall).However,in Australiano seismic behavior is in consideration.So the research on the seismic behavior ofCFFRP has important theoretical significance and engineering value.In this dissertation, the major achievements and the originality innovation areobtained as follows:1,According to the tests of 5 CFFRP Joints specimens of T type underhorizontal-low-cyclic loading with constant vertical loading, fundamental seismicbehavior of such walls and the failure feature have been investigated. Based on thoseabove, comparing the different type of specimens, offering effective reference for laterjoints design of fiber-reinforced plasterboards with core columns.In conclusion,drawing the conclusion that the capacity of shearing force of the T joints is better thanthat of the clay soil brick Joints, offering some testing basis and theoretics guidance ofthe seismic fortification design of the longitudinal and transverse walls joint made ofthe concrete-filled fiber-reinforced plasterboard.2,By using general purpose finite element modeling software-ANSYS, some ofthe T joints are made nonlinear finite-element analysis and develop mechanic analysismodel. based on the stress-strain property of fiber-reinforced plasterboard andreinforced concrete and considering the influences of the nonlinearity and the stiffnessregressing and so on,the nonlinear finite element analysis on the sesmic behavior ofthe CFFRP joint specimens under cyclic loads is carried out by employing thecommand stream edited with ANSYS Parametic Design Language,and by comparisonof analysis results and experimental results,conclusion is obtained that the calculatedresults are much coincided with the tested results.Offering an effective reference forlater computer simulative experiment of CFFRP structure.
