Wind hazard damage estimation was addressed for light steel industrial buildings which were the typical wind vulnerable structures in southeast coastal cities. With parametric analysis of wind damage and the structural failure features, the envelop elements and the connecting elements were determined as the pivots of the damage analysis. Upon the consideration of the co effect of exterior wind pressure, wind induced internal pressure and windborne debris damage, a typhoon load model was proposed. And with the calculation method of the element resistance from the regulation, the procedure of the damage estimation was described and the damage classification of industrial buildings was specified with detailed indicators. Finally, the proposed method was approved with the actual data of typhoon CHANCHU (0601).  相似文献

Low-carbon building is within building’s lifecycle, through carbon source reduction and carbon sink addition during the process of plan, design, construction, operation, demolition and recycle to achieve the optimization of building lifecycle carbon performance. This article takes the case of Low-carbon Building Evaluation Standard of Chongqing to briefly introduce low-carbon building evaluation indexes, also by comparing with the Green Building Evaluation Standard of Chongqing to identify the two index system’s differences and similarities. Through comparison analysis it is discovered that green building evaluation index system focus more on basic resource and energy consumption status as well as the environment quality delivered, where as low-carbon building evaluation index system put more emphasis on detailed resource and energy consumption status and carbon performance.  相似文献

Both the sculpture and architecture belong to plastic art. They involve three-dimensionality, space and object. Connecting the two arts, the sculpture style of buildings shows a special kind of beauty. In this paper, mainly four aspects of how to create the sculptural beauty of buildings are analyzed: repeating and changing gradually; contrasting and omitting; destructing and rebuilding; lighting sense and moving sense.  相似文献

随着非洲猪瘟进入常态化控制阶段,生猪养殖场征地越来越难,而设施农用地建筑高度不能超过两层,不利于生猪养殖企业扩大产能与转型升级。国家首次明确允许楼房养猪,用地面积更少、生物安全性更高,楼房养猪新模式逐渐进入大众视野。结合工程设计实践经验,以尊重猪的生物学特性为出发点,从建设选址、平面、建筑、栏舍等9个角度探讨了工程设计的关键参数。通过楼房养猪工艺设计探讨,结果表明,楼房养猪工艺更精细、更科学,集约化程度更高。楼房养猪具有节约集约用地、生物安全性好、环境质量好、管理效率高诸多优势。本文工艺设计参数为楼房猪场工程建设提供重要理论参考,为楼房养猪产业化发展奠定了理论基础。  相似文献

Different climatic zones should consider different architectural spatial organization forms when designing buildings. In this paper, the design scheme of Half Courtyard located in the Guanzhong Plain of Shaanxi is selected for research to explore how to construct ecological elderly care buildings in cold regions. The design scheme has been proven to increase solar energy efficiency, add natural ventilation, improve the insulation performance of building envelopes, and create a comfortable indoor climate.  相似文献

The density of indoor CO 2 is an important value for newly_built commercial buildings. It affects comercial buildings in two aspects, one is the indoor air_quality, the other is the consumption of energy. The aim of design is to keep good indoor air_quality and using little ventilation. The authors measure a typical department store and analyze the measurement. The conclusion as well as the opinion is given, which argues for improving the efficiency of new_wind.  相似文献

With the problem of the city development, it becomes very important and urgent to research the utilization of the urban underground space. The authors discuss the interaction of high buildings and tunnel which belongs to a project at Dadukou region in Chongqing. The authors simulate this condition in computer and analyses the stress around the tunnel and find the rang of stress concentration. At last,the authors offer some references for underground-space opening of the tunnel under high buildings.  相似文献

According to the industrial character of old industrial basement, such as Chongqing, we select preliminarily the candidated inferior position industries by using DEA analyse model. The synthetical basical coefficient of candidated inferior industries is obtained by analysing their indices such as income elasticity of demand, compared superiority coefficient, compared rate coefficient and technical progress rate, etc. Finally determine inferior industries which was supposed to exit by considing fully society progress and continuable development. A new idea are provided for industral structure adjustment for old industrial basement in China.  相似文献

This paper puts forward a new way in air_conditioning,which combines the fresh_air supply unit and such floor radiation system for the dehumidication and cooling in summer or heating in winter. By analyzing its advantages and limitations, it is found that this so called Cooling/Heating Floor AC System can improve the IAQ of residential building while keep high efficiency quality. It is also recommended that an methodology for the HVAC system designing,which will ensure the reduction of energy cost of users.  相似文献
