以建和中学风雨操场为例，建立了等代钢梁整体模型和实际网架整体模型，通过计算结构动力特性、层间位移角及地震剪力，比较了两种模型的差异，为后续此类结构的设计提供参考。%Taking the Fengyu Playground of Jianhe Middle School as the example,the paper establishes the overall model of the replacement steel beam and the wire frame’s model,and compares the differences between the two models from the calculation of the structural dynamic features, interlayer displacement force,and seismic shearing,so as to provide some reference for the following study on the structure design.
