【摘要】：在全球綠色低碳準(zhǔn)則的影響下,越來(lái)越多的人開始從全生命周期視角重視建筑的低碳性問(wèn)題。因此,“負(fù)碳”的木材成為許多建筑師青睞的建筑材料。中國(guó)城市發(fā)展呈現(xiàn)出高層化的發(fā)展趨勢(shì),高層建筑在一定時(shí)期內(nèi)仍是發(fā)展的重點(diǎn),加上國(guó)外在高層木結(jié)構(gòu)建筑方面已經(jīng)有了很大的突破,因此若可將高層建筑與木建筑相結(jié)合,則既可以滿足高層的建造需求,又可以在建筑全生命周期下解決減少碳排放量的問(wèn)題。因此本文立足于SI理論,提出了一種低碳、靈活、適應(yīng)性強(qiáng)的木結(jié)構(gòu)高層住宅體系。本文提出的SI木結(jié)構(gòu)高層住宅體系分為支撐體和填充體兩部分。支撐體部分采用巨型框架剪力墻結(jié)構(gòu),每三層設(shè)置一處樓板,整個(gè)體系為鋼筋混凝土建造;填充體部分為木結(jié)構(gòu),采用輕型木結(jié)構(gòu)和梁柱結(jié)構(gòu)混合搭建,這兩部分既相互獨(dú)立,又協(xié)調(diào)一致。為保證方案的合理性,本文應(yīng)用PKPM中的SATWE模塊對(duì)原剪力墻方案與新支撐體方案的結(jié)構(gòu)合理性進(jìn)行了驗(yàn)證,通過(guò)對(duì)構(gòu)件參數(shù)進(jìn)行調(diào)整與計(jì)算,使結(jié)構(gòu)體滿足了結(jié)構(gòu)規(guī)范的要求,同時(shí)為下文兩方案的低碳性驗(yàn)證奠定了基礎(chǔ)。為驗(yàn)證新方案在低碳性方面的優(yōu)勢(shì),本文對(duì)原有混凝土剪力墻方案Ⅰ與木結(jié)構(gòu)高層方案Ⅱ進(jìn)行了全生命周期碳排放量驗(yàn)算。計(jì)算對(duì)兩種體系從建材的生產(chǎn)、運(yùn)輸、建筑的建造、運(yùn)行和拆除五部分分別進(jìn)行了碳排放量計(jì)算,得出方案Ⅱ比方案Ⅰ在全生命周期下減少碳排放2 105.76t,減少百分比為3.67%;方案Ⅱ在建材生產(chǎn)和建材運(yùn)輸階段的碳排放量減少比例最大,分別為46.44%和44.23%;方案Ⅱ比方案Ⅰ單位面積排碳量少,每平方米減少碳排放量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，
