中文摘要：
以第一斜杆断裂带生成为结构倒塌标准，以其对应结构峰值加速度为抗震能力指标，计算分析了7个提高结构抗震能力的方案的力学表现，证明在相同用钢量增加比例的情况下，增强横杆截面方案比增强斜杆截面方案更为合理．进一步计算表明屋面重力荷载，矢跨比对结构抗震性能有明显影响。随其变化各方案的费效比表现各异，针对各具体情况，并兼顾用钢量，分别提出了较优方案，对具体工程有一定示范和启发意义。
英文摘要：
Based on the seismic capacity index, the peak ground acceleration at which the fist fracture-beh of shell come into being under severe earthquake. The mechanics performances of 7 seismic patterns is studied and it is proved that those pattern increasing the section of bars is much more effective than those increasing section of diagonals at the same steel volume. More analysis that proof load and ratio of rise-span is influential for seismic capacity and different pattern has different cost-effect ratio. To every situation, the best pattern is presented. The work is demonstrative and instructive value for project.
