Experimental Research And Finite-element Analysis On The L-shape Connection Specimens Made Of Fiber-reiforced Plasterboard

National economic's rapid development and the change of consumer marketmake resident's house become a new hot consumption spot,and replacing the pastchamotte with new wall material is a term of important content of industrialrestructuring .Since China puts forward the concept of "green building materials" forthe first time in November of 2002, wide market prospects has been shown on thegreen building materials'development and use.And at the same time ,higher requeston building materials products has also been proposed.Therefore,we should pay greatattention to the new-type wall material's environmental behavior on its developmentand use.Rapid wall made of fiber-reinforced plasterboard is exactly this newmaterial,which is environmental-protected and of good performance. This article primarily researches on the three L-shape connectionspecimens'basic seismic performance.These specimens are made of rapid wallmaterial with steel and concrete poured in.They are divided to two groups,onedisposed with hoop reinforcement(one specimen ),the other disposed with bindingsteel(two specimens).This article persents the experimental processs and results ofthese specimens under cyclic loading.Failure pattern,bearing capacity,rigiditydegeneration,hysteresis curves and energy dissipation etc.are studiedsystematically.And the seismic performance of the two kinds of specimens is alsocompared synthetically.And the method of nonliner finite-element anslysis software isalso applied to analysis their stress by setting up a practical mechanic model .Theresults of the calculation will be contrasted with that of the test. The results of analysis indicate that the two kinds of reinforcing bars arefundamentally similar in the test.They are finally destroyed by shearing andslipping,and their bearing capacities are almostly equal. The consequence ofcomparison to ordinary multi-floor bricking-up's bearing capacity indicates that thespecimens are satisfied with operating requirements.So they can be used in thepractical project.
