Abstract

Experimentation by producing three-dimensional samples for understanding the seismic behaviour of a structure takes a significant amount of time and these experiments may be highly complicated. Based on literature, the seismic behaviour of structures with slab openings usually was represented by analytical assessments instead of three-dimensional experimental studies. Moreover, the limiting values of slab openings vary greatly between earthquake regulations. This variability has made it important for experimental studies. For this purpose, a total of 5 reinforced concrete carrier system models, with different slab opening ratios, were produced at 1/2 scale. As a result of the study, it was observed that in cases where there were 25% or more openings in the slab, rigid diaphragm behaviour decreased in the structure. It was recommended that for analyses of these types of building systems that the finite element method, based on the assumption of an elastic diaphragm rather than the assumption of a rigid diaphragm, be used.

摘要

通过制作 3D 样本进行实验以了解结构的地震行为需要大量时间，而且这些实验可能非常复杂。根据文献，板式开孔结构的抗震性能通常通过分析评估而不是三维实验研究来表示。此外，楼板开口的极限值在不同的地震法规之间差异很大。这种可变性使其对实验研究很重要。为此，以 1/2 的比例生产了 5 个不同板开度的钢筋混凝土承载系统模型。作为研究的结果，观察到在板坯中有 25% 或更多开口的情况下，结构中的刚性隔板行为会降低。
