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

With analyzing of the case study and based on simulating and analyzing quantitatively , this article , considering the goal of the performance - based fire - protection design is protecting occupants from being injured and keeping buildings from being damaged , thought that fire compartmentation of a large building of saling books can be divided according to their saling malls and fire compartmentation in the saling mall can be separated by the fire - proof screen . on the evacuation design , the quantity of safety exits around these buildings and the evacuation width should be increased if possible and the safety exit number , exit width and evacuation distance can be determined according to the simulating results on smoke layer temperature and height , concentration of co2 and co , occupants evacuation time and visibility . on the means of preventing and discharging smoke , the most proper measure should be determined according to their geometrical characteristics and the natural means of discharging smoke is feasible to the large building of saling books . based on analyzing of smoke 通过对案例分析研究,本文认为大型书城建筑性能化防火设计研究的最终目的是保证人员生命安全和保证建筑结构安全,在模拟计算和量化分析的基础上,大型书城的防火分区可以将中庭连通的书城区域划分为一个区,在书城场地内可以采用防火卷帘进行防火分区划分;在人员疏散设计中,应尽可能利用书城卖场的空间设计较多的安全出口和增大疏散宽度,其安全出口数量、宽度和疏散距离可以根据人员安全疏散时间和烟气温度、沉降高度、 co2浓度、 co浓度、能见度模拟计算结果验证确定;在防排烟方式的选择上,应当根据建筑物的几何特点选取最适宜的措施,就大型书城建筑而言,采用自然排烟的方式是可行的。
