發(fā)音:   用"displacement time"造句

例句與用法

  1. the displacement time history is measured using the displacement sensor
    用位移傳感器量測同一點(diǎn)的位移時(shí)程。
  2. displacement time graph
    位移時(shí)間線圖
  3. 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
    為滿足建筑物大空間和靈活隔斷要求,在高位轉(zhuǎn)換層結(jié)構(gòu)中采用迭層空腹桁架結(jié)構(gòu).首先分析了其受力性能,得出了空腹桁架各構(gòu)件合理的截面剛度以及布局形式.然后結(jié)合一實(shí)際工程,進(jìn)行了兩榀迭層空腹桁架轉(zhuǎn)換結(jié)構(gòu)模型(1:8相似比)的豎向荷載下靜力試驗(yàn)以及擬動(dòng)力試驗(yàn).其中一榀為普通混凝土迭層空腹桁架,另一榀配置了預(yù)應(yīng)力和鋼骨混凝土,對(duì)比分析了兩模型的層間位移比、骨架曲線以及等效粘質(zhì)阻力系數(shù)等抗震性能的比較,并進(jìn)行了彈塑性動(dòng)力分析.試驗(yàn)和分析結(jié)果表明,配置預(yù)應(yīng)力和型鋼混凝土的迭層空腹桁架轉(zhuǎn)換結(jié)構(gòu)具有良好的抗震性能,可以成功地解決迭層空腹桁架作為轉(zhuǎn)換層結(jié)構(gòu)所產(chǎn)生的弊端問題,最后對(duì)這類轉(zhuǎn)換層結(jié)構(gòu)提出了相應(yīng)的設(shè)計(jì)建議
