【摘要】：对山东省青岛市某高层建筑结构设计时上部结构嵌固部位设置的选择进行了研究。对上部结构嵌固部位分别设置在管道夹层的顶板、管道夹层楼板、基础底板三种情况进行计算分析,得出三种选择对工程结构影响的利与弊。研究结果显示,上部结构的嵌固部位首选应设置在主楼±0.000夹层顶板,这种做法不仅满足规范要求,而且从结构受力角度也是最合理的;其次,可考虑把上部结构的嵌固部位设置在基础底板,这种做法同样也是满足规范的要求,但是从结构受力角度来说较不合理,会导致结构造价的增加;最后一种选择是将上部结构的嵌固部位设置在夹层楼板,这种做法从结构设计受力角度也是较为合理的选择,但是无梁楼盖的结构形式不满足规范条文的要求,不提倡这种做法。因此,在实际工程中,上部结构嵌固部位的确定过程往往较为复杂,结构设计人员需要采用包络设计方法,对不同部位的结构模型进行比较计算,取不利值设计,以确保结构的安全。
[Abstract]:The high-rise building structure design of Shandong city in Qingdao province when the upper structure mounted parts set are studied. The upper structure of fixed parts are respectively arranged in the pipe roof sandwich, pipeline mezzanine floor base plate, three cases were calculated and analyzed, obtained three kinds of choices on the structural effects of the advantages and disadvantages. The research results show that the upper structure of the embedded parts of choice should be set in the main building + 0 sandwich roof, this approach not only meet the requirements of the standards, and from the angle of stress is the most reasonable; secondly, the upper part of the structure of the embedded parts is arranged in the base, it also meet the requirements of specification, but from the angle of stress, it is unreasonable, will lead to increased cost of structure; the last one is to choose the upper structure of the fixed parts arranged on the mezzanine floor, this approach from the structural design The stress angle is more reasonable, but the structure of slab-column does not meet the requirements of the regulation, do not advocate this approach. Therefore, in practical engineering, determining the upper structure of the embedded solid parts is often complex, structural designers need to adopt envelope design method, the structure model of different parts of comparison of calculation, take negative value design, to ensure the safety of the structure.
