摘要

摘要: 型钢再生混凝土结构可以将建筑垃圾重新利用，并提高构件的强度和耗能能力。采用开源的地震工程模拟系统OpenSees对7个型钢再生混凝土长柱试件进行全过程非线性数值模拟，分析了在不同再生混凝土取代率、轴压比和体积配箍率下型钢再生混凝土长柱的承载力、延性和耗能能力。在建模过程中，采用纤维模型对型钢再生混凝土柱截面进行细致划分，并对不同截面赋予相应的材料属性，同时结合非线性梁柱单元来完成型钢再生混凝土柱的数值模拟。与试验的对比分析表明，OpenSees能够有效地模拟型钢再生混凝土长柱的受力和变形全过程。

Abstract: Construction waste can be re-used for a steel reinforced recycled aggregate concrete structure，whosestrength and energy dissipation capacity can be improved． In this paper，nonlinear numerical simulation on sevensteel reinforced recycled aggregate concrete( SＲＲC) columns using open-source earthquake engineering simulationsystem OpenSees was carried out． The load-bearing capacity，ductility and energy dissipation capacity under differentrecycled aggregate replacement rate，axial compression ratio and volumetric stirrup ratio of the columns wereanalyzed． In the modeling process，the column section was fine-divided and different fibers were defined to simulatethe appropriate material properties． And then，an model of SＲＲC column was established based on the nonlinearbeam-column element． The comparative analysis of the simulation results and the experimental results indicated thatthe OpenSees can be used to simulate the loading process of steel reinforced recycled aggregate concrete columns．
