(北京市建筑設(shè)計(jì)研究院，100045)［提要］就結(jié)構(gòu)設(shè)計(jì)中的一些概念問題進(jìn)行了討論，內(nèi)容包括：基礎(chǔ)持力層為基巖時抗震要求可適當(dāng)放松，結(jié)構(gòu)抗側(cè)剛度應(yīng)適當(dāng)增加，強(qiáng)風(fēng)低烈度的區(qū)域應(yīng)加強(qiáng)抗風(fēng)設(shè)計(jì)并適當(dāng)放松抗震要求，框剪結(jié)構(gòu)的柱底彎矩可不放大，框支結(jié)構(gòu)的一些問題，不應(yīng)以已建成結(jié)構(gòu)作為設(shè)計(jì)成功的范例，柱軸壓比的限值是否過于嚴(yán)格，以及應(yīng)當(dāng)?shù)种频囊恍┎缓侠淼臉?gòu)造要求。這些討論可作為結(jié)構(gòu)設(shè)計(jì)人員參考。［關(guān)鍵詞］結(jié)構(gòu)設(shè)計(jì)；概念；抗震；抗風(fēng)；構(gòu)造Some Suggestion of Conception of Structure Design/Cheng Maokun(Beijing Institute of Architectural Design,Beijing 100045,China)Abstract: The concept topics about structure design is discussed which are described as follow. Seismic design level can be decreased when the foundation is rock. Its better that the structure is stiffer. The wind resist design is more important than seismic design in regions where wind is intense but earthquake is not intense. The bottom end moment of column of shear－wall－frame structure can not be increased. Something about frame supporting structure should be made more clear. Something which has been used in practice may not be correct sometimes. Pressure ratio of column may be too strict in Chinese regulations. Some details which are not reasonable should be resisted. These discussions may be references to structure designers.Keywords:structure design; conception; seismic; wind; suggestion; construction
