摘要

目前的抗震设计理念允许结构的非线性行为来降低强度要求。这意味着结构必须能够在非线性范围内的位移循环下保持其完整性。结构必须很坚固。对15个系列试验结果的评价表明，在非线性响应范围内，通过能量耗散来抗地震作用的钢筋混凝土柱的极限漂移能力可以简单地通过考虑两个参数来确定:1)长径比，2)横向配筋指数。

Drift Capacity of Reinforced Concrete Columns

The current seismic design philosophy allows nonlinear behavior of the structure to reduce strength requirements. This implies that the structure must be able to retain its integrity under cycles of displacement into the nonlinear range. The structure has to be tough. Evaluation of experimental results from 15 series of tests reported by various investigators has shown that the limiting drift capacity of a reinforced concrete column proportioned to resist earthquake effects through energy dissipation in the nonlinear range of response may be determined simply by considering two parameters: 1) the aspect ratio, and 2) the transverse reinforcement index.
