Finite Element Analysis On Hysteretic Behavior Of Eccentrically Web Members Staggered Truss

Eccentrically web staggered truss is obtained by installing the Y-eccentrically web inthe fasting internodes of staggered truss, in order to improving the seismic behavior ofstaggered truss.Reference an existing test date, the use of finite element software ANSYS simulationof a staggered truss with three internodes under low cyclic loading test, simulation resultsconsistent with experimental date.In order to exploring the best layout form of web in eccentrically web staggered truss,founding the best design of a reasonable length of the energy consumption beam, the paperchange the layout form of web and design7eccentrically web staggered trusses with seveninternodes and4eccentrically web staggered trusses with five internodes; change thelength of the beam energy consumption and design4eccentrically web staggered trusses.Comparativing of various specimens in low cycle hysteretic behavior under cyclicloading.the result shows that hysteretic behavior of eccentrically web members staggered trussis proportional to the number of Y eccentrically web.If layouting more Y-eccentricallyweb,the staggered truss will get better seismic behavior; If layouting more diagonal web,the staggered truss will get better initial stiffness.IF increasing the length of energy beam,the staggered truss will get better seismic behavior and worse initial stiffness.Should beblanced the Y-eccentrically web and diagonal web,as well as the length of the energybeam.The Y eccentrically web may refer to the Y shape eccentrically braced designmethod and conservative design Y eccentrically web.
