摘　　要：以单向斜杆正交正放型单层椭圆抛物面网壳为研究对象,根据不同场地类型和不同设计分组对应的加速度反应谱,利用人工地震波生成程序SIMQKE GR生成了3种设计地震分组和5种场地类型对应的人工地震波。分别对网壳在多遇6、7、8度下的最不利地震进行了研究,挑选出了最不利的场地类型、多遇7度下各类场地类别对应的最不利设计地震分组和网壳的最不利地震持时。One-way diagonals of orthogonal type single elliptic paraboloid shell was used to study according to the different types and designs grouped venues corresponding acceleration response spectrum. The artificial seismic waves were used to generate SIMQKE GR program and designe to generate three types of seismic grouping, and five venues corresponding artificial seismic waves. Reticulated shell in 6,7,8 degrees under the most unfavorable earth- quake are studied, pick out the most unfavorable type of venue, the most unfavorable design earthquake group under 7 degrees and the most unfavorable earthquake excitations of reticulated shell.
