摘要
在简化假设的基础上，导出了规则框架结构自振周期、振型、地震作用、楼层剪力及水平位移等的解析表达式，并制成了图表．利用本文结果，可方便地进行规则框架的抗震设计和计算结果检验．算例表明，本文结果应用于非规则框架的抗震分析时，也具有令人满意的精度．
Based on simplified Models some analytical expressions are derived, which can be usedfor calculating natural periods and modes of vibration, earthquake actions, floor shears and horizontal displacementS of frame structures. Also, several tables and figures are worked out and presented according to these expressions, which can be applied conveniently in the seismic design andchecking computations of frame structures. Some praCtical examples in engineering show that seismic design can be simplified greatly and resultS with satisfactory precision can be obtained byusing the method in this paper for irregular frame structures.
