Analysis Of High-rise Residential Structure System

With the fast development of the residential industry, various house buildings have been emerging just like the bamboo shoots after a spring rain. As a new force, one kind of the buildings which is called the mid-rise house has appeared suddenly and become very popular. Compared with the tier building, the mid-rise house increases the cubage rate of the building with better corollary facilities; compared with the high-rise house building, it has a good many merits such as predominant apartment type, less investment, shorter project duration, lower difficulty, etc. As its use becomes broader and broader, the structural design of the mid-rise house becomes more and more important, especially the selection of structure system and collocation of the structures, which has a direct effect on the security, applicability, and economy of the house. Based on the data analysis and contrast of the technical and economic performance of all kinds of structural systems, the paper gets the differentia of them, votes in relatively reasonable structural types which suits the mid-rise house and provides the basis for the design of the engineering.The paper mainly discusses the aspects as follows:1. Based on the analysis of the functional applicability and structural characteristics of many familiar mid-rise house systems, the paper draws the conclusion that the special-shaped columns frames-shear wall structure, the short pier shear wall structure and the large bay shear wall structure are three kinds of structural systems which are fit for the mid-rise house.2. Applying the three kinds of structural systems to the real engineering, adopting PKPM program soft, inputting the whole model of the structure, the paper gives the calculation and analysis to the structure according to the actual criterion. Based on the contrast and analysis of the technical performance and economic index of the calculating results, the paper finds out the similarities and differences of them in natural frequency, stability of the structure, horizontal displacement, seismic response force, internal force, project cost, and economic index and so on. After this, we can select the relatively reasonable structure which fits the mid-rise house, put forward the design suggestion and provide the reference for the design of the real engineering.3. As far as the special-shaped columns frame-shear wall structure system suitable for...
