【提要】  對現(xiàn)行鋼結(jié)構(gòu)設(shè)計規(guī)范，包括中國規(guī)范（GB50017—2003）、美國規(guī)范（LRFD）、歐洲規(guī)范（EC3）和香港標準（HKC），進行了較詳盡的比較，討論了梁柱設(shè)計的各種原理和流程，總結(jié)了各規(guī)范設(shè)計方法的相似性與不同點。LRFD只利用一個驗算方程來設(shè)計框架柱，而其他三種規(guī)范均需進行截面承載力、平面內(nèi)穩(wěn)定和平面外穩(wěn)定承載力驗算。比較發(fā)現(xiàn)，四種規(guī)范或標準各有優(yōu)缺點，沒有哪一種規(guī)范在各個方面均比其它規(guī)范更為優(yōu)越。
【關(guān)鍵詞】  框架柱  設(shè)計規(guī)范  一致性  差異
Comparison of Present Design Codes or Standards Using for Columns Design in Steel FramesⅠ: Design Approaches/Hou Hetao1，Li Guoqiang2（1 School of Civil Engineering，Shandong University，Jinan 250061，China；2 School of Civil Engineering，Tongji University，Shanghai 200092，China）
Abstract:A detailed comparison of the approaches for design of beamcolumns in steel frameworks specified in the present Chinese（GB50017—2003），American（LRFD），European（EC3） and HongKong（HKC） is presented. The philosophies and procedures for beamcolumn design are discussed and the key similarities and differences among the current approaches are summarized. The LRFD specification employs only a single equation to assess all the possible modes of failure. In contrast，the other three standards employ separate interaction curves for crosssection strength，member inplane strength，and member lateraltorsional strength. It is concluded that all the standards have distinct advantages as well as limitations，and there is no particular philosophical approach given in standards that is clearly superior in all aspects.
