基于能量法的钢骨超高强混凝土柱-混凝土梁节点地震损伤分析
Steel Reinforced Ultra High Strength Concrete Column and Concrete Beam Joints Seismic Damage Analysis and Experimental Research Based on the Method of Energy
摘要
Abstract
In order to study the seismic damage to steel reinforced ultra high strength concrete (SRUHSC) column and reinforced concrete (RC) beam frame joint,seismic damage rule were analyzed on the basis of experimental results of twelve frame joints under low cycle reversed load,the quantitative calculation method of seismic damage were put forward according to the energy equivalence principle,which was assumed that the initial total energy was the work done by the external force on the joints,and the increasing rule of seismic damage index was analyzed.The influence of three kinds of test parameters included stirrup ratios,axial compression ratios and steel bone forms on the damage index were evaluated.Then the seismic damage evaluation model of frame joints was put forward.The results show that the seismic damage index and evaluation model can well reflect the seismic damage characteristics of SRUHSC column and RC beam joints under low cycle reversed load.The research results can provide theoretical reference for the seis mic strengthening repair of SRUHSC column and RC beam joints.关键词
