摘要
就伸臂式结构探讨了上界地震内力理论解的工程实用性。对几种不同质量分布和假设基本振型的计算结果表明,在大多常见情形用主上界做抗震初步设计和验算是方便可行的。
In this paper, the practicality of the theoretical solutions of upper bound seismic inner forces for the cantilever-typed structures in engineering is studied and discussed. The computation results for several different mass distributions and several different hypothetical fundamental modes show that it is convenient and feasible to employ the principal upper bounds for earthquake-resistant checking calculation in majority of practical cases.
