本文对几幢多层砖石结构厂房的实测和试点工程厂房随施工过程的系统试验作了介绍,并对实测结果进行了分析。分析表明多空间作用系数的客观存在,而且由于各层之间相互作用而产生的付空间作用系数与主空间作用系数是同量级的,不可忽视。在对试验结果分析的基础上,提出了多层砖石结构厂房空间工作的分析模型:以具有结点抗转动刚度的“弹性结点排架”作为横向平面体系的计算模型,以等效变剪切刚度梁作为屋盖与楼盖等纵向体系的计算模型。在对单层与多层房屋实测与试验结果分析的基础上,并从偏于安全出发,给出了分析模型中的有关参数。为进一步对空间作用系数的分析提供了依据。
This article introduced the actual measurement of several multi-storey masonry buildings and the pilot plant workshops with the system test of the construction process, and analyzed the measured results. The analysis shows that there is an objective existence of multi-space interaction coefficients, and because the interaction coefficient between the various layers and the main space interaction coefficient are the same magnitude, it cannot be ignored. Based on the analysis of the test results, an analytical model for the spatial work of a multi-storey masonry structure is proposed. The “elastic node truss” with the stiffness of the joints is used as the calculation model of the transverse plane system. The shear stiffness beam is used as the calculation model for the vertical system such as the roof and the floor. Based on the analysis of the actual and test results of single-storey and multi-storey buildings, and starting from partial safety, relevant parameters in the analysis model are given. To provide a basis for further analysis of the spatial interaction coefficient.
