摘要:

为合理确定超长结构的温度与地震作用组合值系数,基于中国6个城市1974年至2023年期间的月平均最高气温、月平均最低气温和年平均气温观测资料,得到正、负温差的概率分布函数,通过卷积公式得到地震与温度作用组合工况随机变量的概率分布,进而根据50年基准期相应的分位值确定温度与地震作用的组合值系数,在此基础上考察相应的可靠指标。结果表明:正温差和负温差均符合极值Ⅰ型分布; 在常见地震和温度作用以及合龙温度的值域范围内,温度与地震作用组合值系数的平均值为0.304 4; 对于温度与多遇地震作用组合工况,当温度与地震作用组合值系数为0.3时,各类结构构件可靠指标的平均值为1.644,高于中国现行《建筑抗震设计规范》(GB 50011—2010)的目标可靠指标,处于较为合理的水平。

Abstract:

In order to reasonably determine the combination value factor of thermal and seismic action for super-long structures, based on the monthly average maximum temperature, monthly average minimum temperature, and annual average temperature observation data of six cities in China from 1974 to 2023, the probability distribution functions of positive and negative temperature differences were obtained. The probability distribution of random variables in the combined condition of earthquake and thermal action was obtained through the convolution formula, and then the combination value factor of thermal and seismic action was determined according to the corresponding percentile value in the 50 years reference period, and the corresponding reliability index was investigated. The results show that both positive and negative thermal differences conform to the extreme value type I distribution. In the range of common earthquake and temperature action and closure temperature, the average value of the combination value factor of thermal and seismic action is 0.304 4. For the case of thermal and frequent seismic action combination, when the combination value factor of thermal and seismic action is 0.3, the average reliability index of various structural components is 1.644, which is higher than the target reliability index of China's current Code for Seismic Design of Building(GB 50011—2010), and its reliability index is at a reasonable level.
