A new nonlinear finite element model which applies subsystem connect beams element and space degenerate shell element to analyze eccentric braced structural energy - dissipation and links collapse mechanism is presented in this paper 本文提出了应用子结构法联合梁单元与空间退化曲壳单元分析偏心支撑钢框架耗能性能及耗能梁段破坏机理的非线性有限元分析模型。
Adding the eccentric brace to the reinforced concrete frame is for strengthening the side stiffness and improving the load - bearing and energy consume ability . when the braced frame resists external force , there is higher side - stiffness at the state of elasticity 在钢筋砼框架结构中加入偏心支撑,其主要目的是提高钢筋砼框架的抗侧刚度、改善框架结构的承载力和耗能能力。
3 ) after investigating the influence of several types of truss on the global ductility of the staggered truss steel framing system , a type of truss which is called scf truss is proposed . the truss act mostly as eccentric braced frames ( ebc ) . the analysis show the scf truss can help improve the global ductility of the staggered truss steel frame with diagonal braces truss 4 )通过不同桁架形式对整体延性的影响作用的分析比较,指出采用本文中给出的sct桁架形式可以在保持抗侧刚度基本不削弱的情况下,较好改善混合交错桁架体系的整体延性性能。
Then at the elastic - plastic state taking advantage of the brace and eccentric distant , we can control the inelastic deformation of the braced frame . the reinforced concrete frames with eccentric brace conform with the earthquake - resistant principle and its seismic properties have improved remarkably . during the lowly circular and repeated loading , the load - bearing , deformation , and ductility of the eccentrically braced reinforced concerete frames were measured 偏心支撑钢筋砼框架的设计意图是当结构在抵抗外力作用时,在弹性阶段结构有较高的抗侧刚度,而当结构进入弹塑性阶段时,利用支撑和耗能段梁的变形使结构的非弹性变形可控,体现了抗震结构“先刚后柔”的原则,使钢筋砼框架的抗震性能得到有效地改善。
