Research On The Application Design Of Timber System In High-rise Residental Buildings Based On SI Theory

Under the influence of global green low carbon standards, more and more people start to pay attention to the low carbon problem of building from the perspective of the whole life cycle. Therefore, the "negative carbon" of the timber has become the building materials for many architects. China's urban development presents a high level of develo pment trend, high-rise building in a certain period of time is still the focus of development, coupled with foreign countries has been a great breakthrough in high-rise buildings, so if the combination of high-rise building and wood building, it can meet t he needs of high-rise building, and can solve the problem of reducing carbon emissions in the whole life cycle. Based on SI theory, this paper presents a low carbon, flexible, adaptive strong wood structure of high-rise residential system.This paper presents the SI wood structure high-rise residential system is divided into two parts, the supporting body part uses a giant frame shear wall structure, each three layers set up a floor, the whole system is reinforced concrete construction; the filling part is wood structure, using light wood structure and beam column structure, these two parts are both independent and coordinated. SATWE module in the application of PKPM structure of the original programme of shear wall and new support scheme verifies the rationality and through the adjustment and calculation of component parameters, and makes the structure to meet the structural requirements specification, as well as below for low carbon verification laid the foundation.On the basis of reasonable structure, thi s paper has carried on the low carbon checking computation to the original concrete shear wall Program 2 and the wood structure high level Program 1. Calculated from the full life cycle, the production of building materials, transportation, construction, o peration and removal of the five part of the calculation, the Program 2 in the whole life cycle to reduce carbon emissions 2 105.76 t, reduce the percentage of 3.67%; and in building materials production and building materials transportation phase of carbon emissions reduction ratio of 46.44% and 44.23%, respectively. Program 2 is 0.55 t per square meter less than Program 1 of carbon emissions reduction.
