摘要

如今,由于社区的不断发展,住宅建筑变得越来越重要。本研究的目的是研究包含轻质承重墙和板的钢结构框架系统的性能,并比较用于经济适用房的冷成型和热加工钢结构系统中使用的材料重量。设计/方法/方法模拟了四种模型,共243个成员。模型1为冷弯型钢结构框架体系,模型2为热加工型钢结构框架体系。模型1和2都使用轻质墙板和轻质复合板。模型3和模型4分别采用砖墙和预制钢筋混凝土体系。这些结构采用不同的墙体和楼板材料,即砖墙和预制钢筋混凝土。分析包括弯曲性能、抗屈曲性能、抗剪切性能和扭转旋转性能分析。研究发现,采用较薄的型钢可以增加挠度值。同时,增加构件长度和长细比会降低构件的抗屈曲能力。随着外加载荷的增大,屈曲变形也随之增大。此外,剪切面积的减小导致剪切阻力的减小。较厚的截面和轻质材料的使用可以降低扭转旋转值。钢结构的重量比较表明,模型1是一种冷弯型钢结构,具有轻质墙板和轻质复合板,由于其重量轻,并且房屋负担得起,是最合适的模型。该模型也可作为土木工程领域冷弯型钢模块化结构框架优化设计的参考和推广工具。

The assessment of structural behaviours of steel framing system – affordable house system design
Purpose Nowadays, residential buildings have become increasingly important due to the growing communities. The purpose of this study is to investigate the behavior of a steel structural framing system that incorporates lightweight load-bearing walls and slabs, and to compare the weight of materials used in cold-formed and hot-finished steel structural systems for affordable housing. Design/methodology/approach Four types of models consisting of 243 members were simulated. Model 1 is a cold-formed steel structural framing system, while Model 2 is a hot-finished steel structural framing system. Both Models 1 and 2 use lightweight wall panels and lightweight composite slabs. Models 3 and 4 are made with brick walls and precast reinforced concrete systems, respectively. These structures use different wall and slab materials, namely, brick walls and precast reinforced concrete. The analysis includes bending behavior, buckling resistance, shear resistance and torsional rotation analysis. Findings This study found that using thinner steel sections can increase the deflection value. Meanwhile, increasing member length and the ratio of slenderness will decrease buckling resistance. As the applied load increases, buckling deformation also increases. Furthermore, decreasing shear area causes a reduction in shear resistance. Thicker sections and the use of lightweight materials can decrease the torsional rotation value. Originality/value The weight comparison of the steel structures shows that Model 1, which is a cold-formed steel structure with lightweight wall panels and lightweight composite slabs, is the most suitable model due to its lightweight and affordability for housing. This model can also be used as a reference for the optimal design of modular structural framing using cold-formed steel materials in the field of civil engineering and as a promotional tool.
