[摘要] 高原環(huán)境模擬實(shí)驗(yàn)室是基于車輛在高原環(huán)境下的使用性能試驗(yàn)而建立的，要求在實(shí)驗(yàn)室內(nèi)模擬低溫、低壓的高原環(huán)境，所以實(shí)驗(yàn)室墻體荷載除了常規(guī)建筑荷載以外，還要承受室內(nèi)外大氣壓差的作用。此外，基于實(shí)驗(yàn)室的特殊使用用途要求，實(shí)驗(yàn)室墻體還需要嚴(yán)格的滿足保溫以及密閉的要求。整體結(jié)構(gòu)形式為剪力墻加支撐，墻體與樓板之問(wèn)的連接為剛性連接，在內(nèi)力分析時(shí)將墻體看成雙向板來(lái)計(jì)算。另外，就墻體保溫措施進(jìn)行了探討。

Abstract: Plateau environment simulation laboratory is establishes based on the vehicles under plateau environment operational performance experiment, simulating the low-temperature, low pressure altitude environment. So the wall of the laboratory not only bears the basic structure and building loads but also bears negative barometric pressure. In addition, for the special function oflaboratory, the walls must have the function ofthermal retardation. The structure form of shear wall with support was adopted and the joint between shear wall and floors lab was rigid. In the internal force analysis the wall was simplified as bidirectional lads. The method of thermal retardation of the wall was researched.
Keywords: plateau environment simulation laboratory; bidirectional lads; the thermal retardation of wall; shear wall
