摘要

本文论述了带有平板的垂直支撑结构连接细节中的应力问题及其可能的分析方法。论文主要关注柱和墙的非轴向连接问题,这是当今建筑设计中的典型问题。参数研究比较了连接垂直支撑结构的距离对不连续区域加固的影响。该区域的应力分析采用了三种不同的计算方法--SCIA Engineer 软件中的线性有限元法、二维支柱和拉杆模型以及 IDEA StatiCa 软件中的二维非线性有限元法。这项研究的结论是比较不同计算方法的准确性,并从剪应力、弯曲应力和具体加固形式的角度对已解决的设计变量进行比较。

Analysis of Position Effect of Vertical Load-Bearing Elements for Reinforcement of Steel Reinforced Concrete Floor Structures
The paper deals with the problem of stress in the connection detail of vertical supporting structures with a flat slab and possible methods for its analysis. It mainly focuses on the problem of non-axial connection of columns and walls, which is typical for today's architectural designs. The parametric study compares the effect of the distance of the connected vertical support structures on reinforcement in the discontinuity region. Three different computational methods are used to stress analysis of this region - linear Finite Elements Method in SCIA Engineer software, 2D Strut-and-Tie Model and 2D non-linear Finite Elements Method in IDEA StatiCa software. The conclusion of the study is a comparison of the accuracy of different calculation methods and also a comparison of the solved design variants in terms of shear and bending stress and specific form of reinforcement.
