位移比 meaning in English
displacement ratio
ratio, displacement
Examples
- Soil quality - determination of the site specific potential for translocation of non - sorbable substances
土质.不可吸附物质位移比能测定 - Conclusions can be drawn from the calculation results that the instantaneous horizontal displacement of the structure fluctuates around the static result and converge to the static displacement because of the influence of damp
从计算结果可以看出，动力分析的水平位移比静力作用的最大水平位移大很多并以静力位移为中心上下波动，并在阻尼作用下收敛到静力位移。 - 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 - Based on the comprehensive statistical analysis of inelastic displacement ratios , the regression equations of - r - t about the strength reduction coefficient and inelastic displacement ratios are obtained . the effects of soil condition , earthquake magnitude , epicenter distance , damp ratios and hysteretic characteristics are considered in detail
通过对理想双线性体系的均值弹塑性位移比与强度折减系数进行了统计分析与数值拟合,建立了两大类场地土(硬土、软土)下的- r - t回归公式。 - Mr . lin tongyan first introduced the detail of irregular graphic in his book " the concept and system of structure " . moreover , in that book he also set some specific parameter for described how a structure will crashed because of that . when quality centre do not coincide with the stiffness centre , will cause a displacement at the same direction with layer components which have different shift , then the structure will torsion around floor ’ s stiffness centre , in some case , it will resulting in severe damage , even let the whole structure crashed
而由于结构形式、平面布置多种多样,令结构自身抵抗扭转的能力也有所不同,因此用同样位移比标准,即“位移比不宜大于1 . 2 ,不应大于1 . 5 ”来描述不同结构形式的不规则特性,可能失之于粗糙,不能很准确地反映出结构的抗扭能力,因此,设想对于结构是否应“被判定为严重不规则结构”的标准,应当联系结构自身抵抗扭转能力大小,予以综合考虑和评价。
