轻钢加层结构中CFRP加固节点地震损伤特征分析
Analysis on the Characteristics of Seismic Damage to the CFRP-Reinforced Joints in Lightweight Steel Storey-Adding Structures
摘要
Abstract
Lightweight steel storey-adding retrofitting technology is one of the effective approaches for urban renewal and renovation of the existing buildings.This paper studies the seismic damage characteristics of lightweight steel storey-adding structure joints reinforced with CFRP by comparing and analyzing the stress of joint anchor bolts,steel bars,CFRP fibers,and the distribution of concrete damage.The results indicate that using CFRP fiber fabric reinforcement can effectively reduce the bearing capacity of steel bars,mitigate plastic damage to concrete,and enhance the seismic performance of lightweight steel storey-adding structures.关键词
