Experimental Studies On Mechanical Performance Of Corrugated Perforated Plate Connectors In Continuous Composite Beams

Composite structure has been considerable development since the last century.Initially,Composite beam is widely used in the form of simply supported beam,but due tothe continuous development of modern architecture,which lead to structural element isconfronted with more and more requirements, and continuous composite beam has itsown advantages,such as stiffness、cost and stress distribution very evenly.Rencentyears,continuous composite beam has been extensively applied to kinds of buildingprojects.In steel-concrete continuous composite beams,whether steel beam and concrete canwork together well depends on the connection, shear connectors play important roles inestablishing the connection.At present, few studies at home and abroad have examinedthe arrangement of shear connectors with thought of the mechanical behavior ofcontinuous composite beams, especially about the new kind of shear connector,corrugated perforated plate connectors. According to the existing research results andapplication, this paper study the connection performance of corrugated perforated plateconnectors in continuous composite beams.This paper designed2steel-concrete continuous composite beams,which hasdifferent arrangements of shear connectors,in order to analyze the effects of differentarrangements on load-slippage rule、load-deflectioncurves and the force situation of shearconnectors, describe their pros and cons,and put forward a reasonable arrangement; inaddition, the paper use the finite element analysis software ABAQUS to establish finiteelement model with spaced arrangement and different kind of factors. Finally analyzingthe effective of several changes on load-slippage rule and connection performance. Thepaper issued recommendations for the arrangement of shear connectors, which based onthe test results and the simulation results.Finally,by means of regression analysis,thepreliminary calculation formula for shear stiffness is presented.The results providereference for subsequent research work and application of corrugated perforated plateconnectors.
