| Structural progressive collapse has occurred a short time, large-scale destruction,causing serious loss of life and property, thus increasingly subject to the public’s and theresearchers’ attention. Analysis of most of the present research at home and abroad inthe frame structure to resist progressive collapse, but the related research of reinforcedconcrete frame-shear wall structure is relatively less. Reinforced concrete frame-shearwall structure in Chinese urban construction is used more, its resistant progressivecollapse performance to guarantee people’s life safety and reduce the loss of propertieshave important significance. Therefore, this paper using SAP2000finite elementanalysis software for reinforced concrete frame-shear wall structure performance toresist progressive collapse analysis by using the alternate load path method, the mainresearch contents are as follows:（1）Respectively analyze the influence of the internal forces and displacements ofthe frame structure and frame-shear wall structure after the demolition of the underlyingcolumns at different locations by using the linear static analysis method and lineardynamic analysis method.（2）Respectively analyze the influence of the plastic hinge development law, theultimate bearing capacity and ductility after the demolition of the underlying columns atdifferent locations by using the nonlinear static analysis method.（3）Analyze and compare the similarities and differences of the internal forces,deformation, ultimate strength and ductility between the frame structure andframe-shear wall structure after the demolition of the underlying columns at same locations by using the linear static analysis, nonlinear static and linear dynamic analysismethods.（4）Analyze and compare the influence between the remaining frame structureand the remaining frame-shear wall structure after the demolition of all pillaredcompared with only removal of the underlying column by using the linear dynamicanalysis method. |
