摘要
基于能量抗震设计是以能量平衡为基础,通过结构的能量方程,分析地震能量输入、转化和耗散,从而控制能量转化途径。本文主要介绍了基于能量抗震设计中结构总输入能量、能量分配、阻尼耗能、滞回耗能的计算方法等。探讨了基于能量抗震设计方法存在的不足以及未来发展趋势。
Earthquake-resistant calculation method for buildings based on energy balance is based on energy balance, through the energy equation, and analyze the input energy of earthquake, conversion and dissipation, so as to control ways of energy conversion. The main contents of this paper are introduced the calculation method of the total input energy in the earthquake, energy distribution, damping energy and hysteretic energy in earthquake-resistant calculati-on method for buildings based on energy balance. And, this paper discusses the existing shortage and alternative in the future of earthquake-resistant calculation method for buildings based on energy balance.
