[摘要] 簡(jiǎn)要介紹了ASCE 7-05風(fēng)荷載的計(jì)算方法,并與國(guó)標(biāo)規(guī)范進(jìn)行對(duì)比。重點(diǎn)考察了兩本規(guī)范在基本風(fēng)速、體型系數(shù)、荷載工況方面的不同,以便更好在地理解和運(yùn)用ASCE 7-05中風(fēng)荷載相關(guān)內(nèi)容。利用STAAD.Pro,結(jié)合實(shí)際工程算例,進(jìn)行風(fēng)荷載作用下的結(jié)構(gòu)計(jì)算,以便類似工程的設(shè)計(jì)參考。[關(guān)鍵詞] ASCE 7-05;風(fēng)荷載;基本風(fēng)速;體型系數(shù);荷載工況;STAAD.Pro

Difference of basic wind speed, pressure coefficient and design wind load cases between the two codes are considered. A design example of wind calculation is introduced, with STAAD.Pro as CAE software. The article can be reference for structure design of similar projects.Keywords:ASCE 7-05;wind load;basic wind speed;pressure coefficient;load cases;STAAD.Pro
