摘要:
为了减轻传统建筑在地震中的位移响应，提升减震效果，研究三种地震波下减震框架抗震性能数值模拟。应用数值模拟软件，分别设计传统建筑的钢筋混凝土纯框架以及三种具有不同阻尼参数的减震框架，并在KJM波形、EUR波形和人工波形三种地震波下分析每种框架的抗震性能。数值模拟结果表明：钢筋混凝土纯框架在地震作用下的位移、层间剪力和层间位移角变化均最为显著，表明其抗震性能相对较弱；三种减震框架在不同地震波形下均表现出较小的位移、层间剪力和层间位移角变化，抗震性能较佳。速度指数为0.30α，阻尼系数为320kN/（m/s）0.15的方案三减震框架抗震性能最佳，其位移、层间剪力和层间位移角变化均为最小。
Abstract:
To mitigate the displacement response of conventional buildings under seismic action and enhance the ef‐fectiveness of seismic reduction, this study investigates the seismic performance of energy-dissipating frames through numerical simulations under three types of seismic waves. Using numerical simulation software, a reinforced concrete pure frames was designed for traditional buildings, along with three types of energy-dissipating frames with different damping parameters. The seismic performance of each frame was analyzed under three seismic waves:KJM, EUR, and an artificially generated waveform. Numerical simulation results show that the reinforced concrete bare frame exhibits the most significant variations in displacement, inter-story shear force, and inter-story drift angle under seismic excitation, reflecting its relatively weak seismic performance. In contrase, the three energy-dissipating frames exhibit relatively smaller displacement, inter story shear force, and inter story drift angle across different seis‐mic waveforms, demonstrating improved seismic performance. Among these, the third energy-dissipating frame—with a velocity exponent of 0.30α and a damping coefficient of 320 kN/(m/s) 0.15—performs the best, exhibiting the minimal variations in displacement, inter story shear force, and inter story displacement angle.
