一、前言新建建筑抗震设防、已有老旧建筑抗震加固是长期以来国内外工程技术人员对建筑物抵御地震所采用的普遍途径,即工程抗震与抗震设防。进行抗震设防的建筑物,具有一定的强度与变形、抗倒塌能力。但抗震建筑在地震中是以建筑物本身的变形、开裂、破坏为代价来抵抗地震的,是“以刚克刚”。随着社会和技术的不断进步,人们对建筑功能及安全性提出的要求越来越 I. INTRODUCTION The seismic resistance of newly-built buildings and the seismic reinforcement of existing old buildings is a long-term universal approach adopted by engineers and technicians at home and abroad to resist buildings from earthquakes, ie seismic and seismic fortification of the project. Buildings with seismic fortification have a certain degree of strength, deformation, and collapse resistance. However, earthquake-resistant buildings resist earthquakes at the expense of deformation, cracking, and damage to the buildings themselves in the earthquake. With the continuous advancement of society and technology, people are increasingly demanding architectural functions and safety.
