135Degrees L Section Of The Special-shaped Columns Oblique Section Bearing Capacity Calculation Method And Seismic Performance Analysis

Along with our country housing development,a kind of new building structuresystem-shaped column structure system generates,special-shaped columns generallyrefers to cross section shape for the L、T、十and Z, cross section limb high andappendage thick or less than4reinforced concrete frame column.This kind of structuresystem to avoid the disadvantages of the traditional architectural structure,make thebuilding interior not dew edge,beautiful tidy,has the good building use function,increase the building usable floor area.Since the concrete special-shaped columnsstructure technical regulation in the cross section shape is limited,so this paper first putsforward135degrees L section reinforced concrete special-shaped columns.This paper by the use of finite element software ADINA to135degrees L sectionreinforced concrete special-shaped columns of oblique section bearing capacitycalculation method and structural seismic performance are analyzed,and based on this,advances the special-shaped columns in this for engineering application of beneficialSuggestions,the this article main work is as follows:(1) To analyze the concrete special-shaped columns structure technical regulationstructures in the inclined section shear bearing capacity of the composition andcalculation method,the analysis of the others,and with reference to the data, using thefinite element software numerical simulation analysis,and finally from the limit bearingcapacity,member under low-cyclic reversed loading the hysteresis curve,componentfailure of shear stress nephogram and so on contrast, analysis of the experimental resultsand simulation for deviation between the data,using the finite element softwarevalidation of numerical simulation analysis is feasible.(2) Considering the flange of component shear bearing capacity of the influences ofdifferent component loading Angle simulation analysis,according to the structure designof the most unfavorable principle,determine the unfavorable loading Angle.From theshear span ratio,axial compression ratio and stirrup configuration three different factorsto the change of special-shaped columns component, numerical simulation analysis,analysis the simulation results of the ultimate bearing capacity and theoretical agreement between whether,in accordance with the regulations of the analysis methodsfor calculating the reliability of the calculation.(3) From the shear span ratio,axial compression ratio and stirrup configurationthree aspects,to135degrees L section of reinforced concrete special-shaped columnsaseismic behavior of finite element analysis.From the hysteresis curves, skeleton curvesdirections,and the analysis of three parameters variations on the influence of thespecial-shaped columns seismic performance.
