砌体结构具有辉煌的历史,随着建筑业的发展,砌体结构的处境十分艰难。文章分析了国家的“禁实限黏”政策的影响、传统砌体块材外观质量的局限、未经正常设计的砌体建筑抗震性能缺陷以及城市建筑向高层发展挤压了砌体结构的生存空间,厘清了砌体结构发展存在的问题。在国家“双碳”目标下,砌体结构建筑的可持续性能够很好地适应城镇绿色低碳建设及新农村低层建筑的建设需求,是砌体结构建筑发展的良好机遇;从高性能砌体材料、固体废弃物资源化、砌体结构适用范围与标准、抗震性能、村镇低层砌体建筑简化建造、复合墙体和配筋砌体、装配式建筑与智能建造等方面入手,分析了砌体结构的现状及所面临的机遇,提出了砌体结构的发展方向及其相应的技术措施。 相似文献

在正确分析一 30 层高住宅楼倾斜原因的基础上,对该楼纠倾加固工程采取的纠倾加固措施以及控制技术进行了针对性的研究。为确保该倾斜建筑物安全、平稳、线性的回归,本工程通过首次采用“基底掏土为主,锚索加压为辅”的组合纠倾方法,对应力控制、锚索加压调控及变形控制等多重纠倾控制技术进行深入的研究,而后制定科学合理的施工工序,最终保证了该高层建筑物纠倾加固工程的成功实施,大楼倾斜率由纠倾前的 2.66‰ 回归到 0.87‰ ,满足了国家相关规范及正常实用要求,本工程在纠倾高度( 97 m )及层数( 30 层)方面,刷新了国内高层建筑物纠倾纪录,填补了在强风化泥岩、复杂地基、深埋基础中实施双向纠倾的空白,对高层建筑物的纠倾具有很高的借鉴价值。 相似文献

The number of airtight buildings equipped with air-conditioning units along with levels of energy consumption from residential and commercial buildings has both increased markedly in China since 1990 due to rapid economic growth and urbanization. During this same period, home refurbishment/decoration/remodeling activities in newly constructed or existing apartments have become very popular and brought attention to a wide range of health concerns. This paper reviews building energy-saving and indoor-air-quality (IAQ) related standards in China. In summary, the two systems of building energy-saving and IAQ-related standards have been already established separately, although Chinese IAQ standards contain some indices related to building ventilation and energy (e.g. fresh air volume, relative humidity, and temperature). Building energy-saving systems are applicable to buildings existing in a wide range of climatic conditions. Formaldehyde was selected as a pollution index in “Chinese Evaluation Handbook of Ecological Residence Technology” (promulgated in 2001) for buildings mainly contaminated with harmful compounds emitted from interior decorating materials. As part of its IAQ control strategy, China promulgated a series of IAQ-related standards and compulsory national standards for limits of harmful substances contained in interior decorative materials (LHSCIDM), which placed strong emphasis on source control. When enacting the IAQ-related standards, China adopted some of the standards used in developed countries and related international standards for reference. 相似文献

Building regulations vary internationally in their objectives and in the responsibilities they place upon designers and contractors, but they generally depend upon national or international codes and standards for their technical requirements. The systems operated in a number of European countries are discussed in this paper in terms of the internal environment of buildings and general considerations of public safety and health. The author refers to the influence of the relevant CIB Working Commissions in establishing internationally agreed standards for the internal environment of buildings and performance concepts. 相似文献
