摘要利用有限元分析软件，对空间钢筋混凝土交错空腹桁架结构进行线性模态分析。 - To meet the demands for large space and flexible compartmentation of buildings , laminated vierendeel trusses are adopted in high - position transfer story structures . first the bearing characteristics are analyzed , in which reasonable stiffness ratio of the upper chord , middle chord , and lower chord is derived . then combined with an actual engineering model ( 1 8 similar ratio ) , the static loading and pseudo - dynamic tests of two models for laminated vierendeel truss used in transfer story structures are conducted , in which one model adopts reinforced concrete , and the other adopts prestressed concrete and shape steel concrete . seismic behaviors are analyzed , including inter - story displacement , base shear - displacement skeleton curves , and equivalent viscosity - damping curves . a program is programmed to carry out the elasto - plastic dynamic analysis , and displacement time - history curves of the two models are derived . the test and analysis results show that the laminated vierendeel truss with prestressed concrete and shape steel concrete has excellent seismic behaviors . it can solve the disadvantages of laminated vierendeel trusses used in transfer story structures . finally , some design suggestions are put forward , which can be referenced by similar engineering
为满足建筑物大空间和灵活隔断要求,在高位转换层结构中采用迭层空腹桁架结构.首先分析了其受力性能,得出了空腹桁架各构件合理的截面刚度以及布局形式.然后结合一实际工程,进行了两榀迭层空腹桁架转换结构模型( 1 : 8相似比)的竖向荷载下静力试验以及拟动力试验.其中一榀为普通混凝土迭层空腹桁架,另一榀配置了预应力和钢骨混凝土,对比分析了两模型的层间位移比、骨架曲线以及等效粘质阻力系数等抗震性能的比较,并进行了弹塑性动力分析.试验和分析结果表明,配置预应力和型钢混凝土的迭层空腹桁架转换结构具有良好的抗震性能,可以成功地解决迭层空腹桁架作为转换层结构所产生的弊端问题,最后对这类转换层结构提出了相应的设计建议 - The paper also carried out elastic and plastic analysis on 8 - storeyed truss and 8 - storeyed vierendeel truss . based on the results , the two structures can both be applied to strong earthquake zone . however , the weak layer of the former structure is the first storey , while the weak layer of the latter is the 3rd storey
本文还对8层的混合式钢结构交错桁架体系、 8层的空腹式交错桁架体系的进行了弹性和弹塑性分析，从分析结果中可以看出， 8层的两种形式的结构都适合用于8度强震区的三类场地土区，但混合式的薄弱层是在结构底层，而空腹式的薄弱层是在结构的第3层，而且两者的破坏模式也有所不同。
