Design And Study On The Structrue System Of A High-rise Residential Buildings

Along with society's development and people living standard enhancement. The housing demand of people is greatly increase. The request to the housing quality is more and more enhanced. Because the land supplies and the city land resource is becoming more and more limited day by day. Population old age, the resident yearns for the city life necessary desire is intense, urges the housing shape further to raise to high level and is small high level develops.The Short-leg Shear wall is a new type of structure to resist lateral loads in recent years. It has got widely used in high-rise buildings due to its fine lateral stiffness ability and no extrusive part. However, there are no complete theories available to guide the design of this type of shear walls due to the lack of research on it. As a matter of fact, the performances of short piers. Therefore, further theoretical analysis and experimental studies are extremely essential.A theoretical study on the height to thickness ratio of the in shear walls with short piers system is theoretically conducted in the thesis. Structure testing investigations about shear wall with short piers are collected and introduced in thesis, on which discussions are carried out in two point of view, as single component and as structure. The ductility of the whole Short-pier Shear wall structure is better than that of single component with asymmetric cross section. Further more, almost all of the cycle loading tests at low frequency and shaking table tests show the same results, that the shear wall system with short piers has beam hinge and better capacity of deformation and energy dissipation, which forms good bases for design of that kind of structure system.In the thesis, a residential building project is taken as an example, to which FEA analysis are carried out with wall element model. Rational arrangement and computation module are chosen through analyes and comparison to design parameters and indexes. The Push-over method in the EPSA software is taken to check the anti-collapse of shear wall structure with short pier and verify the beam hinges in kind of structure system to find out weak level.Moreover, through comparation and analysis to two kind of structures designs of used in one housing project, simply introduces the steel structure system and the great standard width of a room opening -like Short-pier Shear wall structure system.Through several projects examples structure system analyes, this article summarizes some designs experiences, supplies to refer.
