摘要:
针对部分在役钢筋混凝土（RC）框架结构因抗震设计标准更新及材料性能退化而难以满足现行抗震要求的问题，提出一种基于随机函数表达的非平稳人工地震动模拟方法。首先，在传统Monte Carlo模拟基础上引入随机正交函数，仅采用一个基本随机变量即可生成满足工程精度要求的非平稳人工地震动样本，且其反应谱与规范反应谱吻合良好。随后，以四川宝兴地区一栋10层在役RC框架结构为工程背景，分别采用剪力墙和3种屈曲约束支撑（BRB）形式进行抗震加固，并基于周期比和最大层间位移角评价不同加固方案的抗震性能。结果表明：该方法具有样本需求少、计算效率高和可重现性好的特点；不同加固方案均能提高结构抗震性能，其中人字型BRB在降低周期比、控制层间位移角和减弱扭转效应方面效果最佳，综合抗震性能优于其余两种BRB形式；相比剪力墙加固，BRB无需湿作业，更具工程应用优势。研究结果可为在役RC框架结构抗震加固设计提供参考。
Abstract:
Against the backdrop that many in-service reinforced concrete (RC) frame structures fail to comply with current seismic criteria owing to updated seismic codes and degraded material performance，we proposed a simulation method for non-stationary artificial ground motions based on random function representations. First, Random orthogonal functions were incorporated into conventional Monte Carlo simulation. The proposed method only required a single basic random variable to generate non-stationary artificial ground motion samples meeting engineering precision, and the corresponding response spectra matched the code-specified spectra well. Then, a 10-story in-service RC frame structure in Baoxing, Sichuan Province, was taken as the engineering prototype. Shear walls and three types of buckling-restrained braces (BRBs) were utilized for seismic retrofitting, and the corresponding seismic performance was evaluated in terms of period ratio and maximum inter-story drift angle. Results showed that the proposed method features fewer required samples, high computational efficiency and favorable reproducibility. All retrofitting measures can enhance structural seismic performance. The herringbone BRB achieves optimal comprehensive seismic performance in reducing period ratios, restraining inter-story drift angles and alleviating torsional effects, superior to the other two BRB types. Unlike shear wall retrofitting, BRB installation involves no wet construction, presenting prominent advantages in practical engineering. The findings provide technical references for retrofitting design of in-service RC frame structures.
