一、前言对大多数钢筋混凝土房屋来说,经济而安全的抗震设计目标是:在遭遇设计地震烈度时建筑物不需要修理或经一般修理仍可继续使用,这大体相当于或轻于中等程度的破坏。在更强烈的地震作用下,尽可能防止结构的倒塌。要实现这样的抗震设计目标,对某些建筑结构就要进行抗震变形验算,并根据不同要求控制结构的变形。本文讨论了钢筋混凝土结构及其构件的变形性能,并根据试验资料和工程经验,初步提出不同情况下容许变形指标,供结构变形验算时参考。二、衡量结构地震变形能力的指标众所周知,地震时结构处于地震的能量场内,随着地震能量的输入,结构有一个复
I. INTRODUCTION For most reinforced concrete buildings, the objective of an economical and safe seismic design is that if the design earthquake intensity is encountered, the building can be used without repairs or general repairs, which is roughly equivalent to or lighter than moderate. The destruction. Under more intense earthquakes, as far as possible to prevent the collapse of the structure. To achieve such seismic design goals, seismic deformation calculations must be performed for certain building structures, and structural deformations should be controlled according to different requirements. This article discusses the deformation properties of reinforced concrete structures and their components, and according to experimental data and engineering experience, initially proposes the allowable deformation index under different conditions for reference in the calculation of structural deformation. Second, the indicators to measure the structure of seismic deformation capacity As we all know, the structure of the earthquake is in the energy field of the earthquake, with the input of seismic energy, the structure has a complex
