［摘要］回顧了國家標(biāo)準(zhǔn)《建筑結(jié)構(gòu)荷載規(guī)范》編制修訂的發(fā)展歷程，總結(jié)歸納各版本的主要內(nèi)容及技術(shù)特點。該規(guī)范自20世紀(jì)50年代誕生以來共有5個主要的修訂版本。1954年發(fā)布的最初版本（結(jié)規(guī)-1-54）以引進(jìn)吸收國外標(biāo)準(zhǔn)為主。我國自主研編的1974年版本（TJ 9-74）內(nèi)容基本本地化且較為完整。1987年版本（GBJ 9-87）采納基于概率的極限狀態(tài)設(shè)計方法，并進(jìn)行了大規(guī)模的荷載調(diào)查和活荷載組合方法研究，使本標(biāo)準(zhǔn)進(jìn)入國際先進(jìn)標(biāo)準(zhǔn)的行列?，F(xiàn)行的2012年版本（GB 50009—2012）不僅針對大跨和超高層建筑結(jié)構(gòu)設(shè)計需求補充完善了大量風(fēng)荷載、雪荷載內(nèi)容，還新增了溫度作用和偶然荷載，規(guī)范的適應(yīng)性和技術(shù)水準(zhǔn)顯著提升。根據(jù)國家工程標(biāo)準(zhǔn)改革的部署，該規(guī)范內(nèi)容將納入正在編制中的全文強制規(guī)范中，適用范圍擴(kuò)展到工程結(jié)構(gòu)，取值水準(zhǔn)也將適當(dāng)提高，以提升我國的結(jié)構(gòu)可靠性水準(zhǔn)，并與國際標(biāo)準(zhǔn)接軌。

Abstract:The development course of compilation and revision of the national standard Load Code for the Design of Building Structures was reviewed, and the main contents and technical characteristics of each edition were summarized. Since its birth in the 1950s, there have been five major revisions of the code. The first edition (structural code 1-54) published in 1954 mainly introduced and absorbed contents of foreign standards. The content of the 1974 edition (TJ 9-74) independently edited by China was basically localized and relatively complete. The 1987 edition (GBJ 9-87) adopted the probability-based limit state design method, and carried out large-scale load investigation and live load combination method research, making this standard rank among the international advanced standards. The current version of 2012 (GB 50009—2012) not only improves a lot of wind and snow loads, but also adds temperature effects and accidental loads to meet the structural design requirements of large-span and super high-rise buildings. The adaptability and technical level of the code have been significantly improved. According to the deployment of the national engineering standard reform, the content of the code will be included in the full-text compulsory code being compiled. The scope of application will be extended to the engineering structure, and the value level will be improved appropriately, so as to improve the reliability level of China′s structure and conform to international standards.
Keywords:building structure; load code; characteristic value; full-text compulsory code; reliability level
