高层建筑结构抗风可靠性研究进展

Research Progress of Wind Reliability of Highrise Buildings

回顾并总结了建筑结构可靠性评价标准、可靠性动静态分析方法和考虑风向的可靠性分析方法等几个涉及结构抗风可靠性问题的国内外研究成果,同时对多国荷载规范中关于风向和抗风可靠性的规定进行了讨论.通过分析结构可靠性的评判准则、研究方法、结构动力响应参数、风向等多个因素对结构抗风可靠性的影响以及现有研究方法中所存在的问题,指出当前结构抗风可靠性研究中存在的不足,并提出了进一步研究的建议.

By reviewing the researches of structural reliability under wind loads, such as evaluation standard, static and dynamic analysis, and directional analysis, wind direction effect and wind- reliability, the wind direction effect and wind reliability in the load codes of various countries were discussed. In addition to the evaluation method of reliability, dynamic parameters, influence of wind direction on reliability and the deficiencies of present researches were analyzed. Suggestions for further research are also proposed in the end.
