Research On Mechanical Properties Of Special-Shaped Columns Structures With Reduced Columns At The Bottom And Transfer Storie

With the rapid development of China’s housing industry, people in the pursuit of comfort at the same time began to increasingly focus on the beauty and diversity of structural arrangements, from the past to meet the requirements of functions and units to the rational development of the current housing itself comfortable livable, thermal insulation, seismic and other comprehensive security performance requirements. Shaped column frame structure as a new building structures, but not in its interior corners, around parapets and walls thinner, increasing the use of space, to make up for the lack of rectangular columns. Especially with the2006"Technical Specification for Structural Concrete Columns"(JGJ149-2006) to promulgate, implement, shaped column structure for the development and application played a positive role.But with the functional requirements of the building with increasingly high, the bottom of1to2layers often used in supermarkets, as a parking occasionally require a large space to the bottom of the structure and the upper column system was shaped. To derive a new type of architectural building system-the bottom of the pump cylinder shaped column with a conversion layer systems that are more popular in the present study as a building structure, a lot of relevant papers have carried out research, but its application, security and many other issues had not been completed. Based on a seven-storey bottom pumping column shaped column with a conversion layer framework for multi-use SAP2000under earthquake response spectrum analysis, multi-event and under rare earthquake time history analysis, conversion layer in the direction of the static nonlinear Pushover analysis to study the location of its conversion layer structure is not the same right under earthquake seismic performance, in order to propose feasible structural solutions for practical use.
