【Abstract】 Single - shear - plate connection is usually considered as pin connection in the design of SRC composite structure. In fact, restraining moment exists in the connection. Up to now, research is limted at connection between steel plate girder and RC shear wall. Considering Beijing LG Tower design as an example, finite element analyses of single - shear - plate connection between steel truss and RC core wall are carried out. Results show that the restraining moment are related to many factors, such as piate thickness, bolt diameter, span and height of steel truss etc. Based on analysis results, formula for the calculation of restraining moment of single - shear - plate connection between steel truss and RC core wall is derived.更多还原
