风荷载是高耸结构的主要设计荷载,由于我国建设的迅速发展,原来的部分条文已不能适应当前实际工程的需要。基于研究的不断进展、荷载规范的修订变化和国外相关规范的接轨适应,高耸结构设计规范风荷载条文的修订已迫在眉睫。本文对主要部分:基本风压、地貌、风压高度变化系数和横风向共振响应作了详细的研究和分析。
Wind load is the main design load of towering structures. Due to the rapid development of our country’s construction, some of the original provisions can no longer meet the needs of the current practical projects. Based on the continuous progress of the research, the revision of load regulations and the adaptation of relevant foreign regulations, the revision of the wind load regulations for tall structural design codes is imminent. The main parts of this paper are: basic wind pressure, geomorphology, wind pressure height variation coefficient and transverse wind resonance response.
