【摘要】：在全球绿色低碳准则的影响下,越来越多的人开始从全生命周期视角重视建筑的低碳性问题。因此,“负碳”的木材成为许多建筑师青睐的建筑材料。中国城市发展呈现出高层化的发展趋势,高层建筑在一定时期内仍是发展的重点,加上国外在高层木结构建筑方面已经有了很大的突破,因此若可将高层建筑与木建筑相结合,则既可以满足高层的建造需求,又可以在建筑全生命周期下解决减少碳排放量的问题。因此本文立足于SI理论,提出了一种低碳、灵活、适应性强的木结构高层住宅体系。本文提出的SI木结构高层住宅体系分为支撑体和填充体两部分。支撑体部分采用巨型框架剪力墙结构,每三层设置一处楼板,整个体系为钢筋混凝土建造;填充体部分为木结构,采用轻型木结构和梁柱结构混合搭建,这两部分既相互独立,又协调一致。为保证方案的合理性,本文应用PKPM中的SATWE模块对原剪力墙方案与新支撑体方案的结构合理性进行了验证,通过对构件参数进行调整与计算,使结构体满足了结构规范的要求,同时为下文两方案的低碳性验证奠定了基础。为验证新方案在低碳性方面的优势,本文对原有混凝土剪力墙方案Ⅰ与木结构高层方案Ⅱ进行了全生命周期碳排放量验算。计算对两种体系从建材的生产、运输、建筑的建造、运行和拆除五部分分别进行了碳排放量计算,得出方案Ⅱ比方案Ⅰ在全生命周期下减少碳排放2 105.76t,减少百分比为3.67%;方案Ⅱ在建材生产和建材运输阶段的碳排放量减少比例最大,分别为46.44%和44.23%;方案Ⅱ比方案Ⅰ单位面积排碳量少,每平方米减少碳排放量0.55t。
[Abstract]:Under the influence of global green low-carbon standards, more and more people begin to attach importance to the low-carbon nature of buildings from the perspective of the whole life cycle. As a result, "negative carbon" wood has become a building material favoured by many architects. China's urban development shows a trend of high-rise development, high-rise buildings are still the focus of development in a certain period of time, and foreign countries have made a great breakthrough in high-rise wooden buildings, so if high-rise buildings and wood buildings can be combined, It can not only meet the needs of high-rise buildings, but also solve the problem of reducing carbon emissions in the whole life cycle of buildings. Therefore, based on SI theory, this paper puts forward a low carbon, flexible, adaptable wood structure high-rise housing system. The high-rise building system of SI wood structure is divided into two parts: support body and filling body. The support part is composed of a huge frame shear wall structure with a floor every three stories, and the whole system is built of reinforced concrete, and the filling part is a wood structure, which is composed of light wood structure and Liang Zhu structure, and the two parts are independent of each other. And coordinated. In order to ensure the rationality of the scheme, the structural rationality of the original shear wall scheme and the new support scheme is verified by using the SATWE module in PKPM. By adjusting and calculating the component parameters, the structure can meet the requirements of the structural code. At the same time for the following two schemes of low-carbon verification laid the foundation. In order to verify the advantages of the new scheme in the aspect of low carbon property, the whole life cycle carbon emissions of the original concrete shear wall scheme I and the wood structure high-rise scheme II are checked and calculated in this paper. The carbon emissions of the two systems are calculated separately from the production, transportation, construction, operation and demolition of building materials. It is concluded that the carbon emissions of scenario II are reduced by 2 105.76 t, or by 3.67%, over the whole life cycle, and that the reduction of carbon emissions in the stage of building materials production and construction materials transportation is the largest in scenario II. It was 46.44% and 44.23%, respectively, the carbon emission of scheme 鈪，
