多层单跨框架结构加固设计应用研究分析

Applied Research and Analysis on Reinforcement Design of Multi-layer and Single-span Frame Structure

在对现有建筑物进行加固改造设计时,需要对现有建筑物进行安全鉴定和结构分析,并制定科学合理的加固设计方案,方能取得理想的加固效果。本文针对重点设防类别(乙类)的多层单跨框架结构建筑物,从建筑结构安全角度从发,依据建筑抗震鉴定标准、建筑抗震加固技术规程和建筑抗震设计规范等现行规范规程的规定,通过理论研究与计算模型对比分析,从中得到此类建筑物结构加固设计的有效方法。

Safety appraisal and structural analysis are required in designing the scheme for reinforcement and reconstruction of buildings,besides scientific and reasonable reinforcement design plan is needed in achieving the desirable reinforcement effect.This paper aims at analyzing multi-layer single-span frame structure of the key fortification category (category B),it conducts theoretical research and comparative analysis on computational model from the perspective of building structure safety in accordance with the current normative regulations such as seismic appraisal standards for buildings,technical regulations for seismic strengthening of buildings and seismic design codes for buildings in order to conclude an effective method for structural reinforcement design of such buildings.
