摘要
文章以江苏省无锡市某农贸市场为例,通过对现状的研究与分析,从优化空间结构、合理动线及采用自然通风和采光的角度提出优化设计策略,实现建筑设计目标,并选用混凝土薄壳结构作为主要建筑形式。同时,利用ABAQUS有限元软件对结构的关键构件自由曲面屋顶进行建模和数值仿真计算分析,探究结构在屋面荷载作用下的力学性能。结果表明:曲面薄壳能够较好地传递应力,减小自身的挠度。增大曲面的厚度可以有效减小结构整体的最大应力和底部圈梁的最大支座反力。
Taking a farmer market in Wuxi city,Jiangsu province as an example,through the research and analysis of the current situation,this paper puts forward the optional design strategy from the perspective of optimizing the spatial structure,rational moving line and adopting natural ventilation and lighting to achieve the architectural design goal,and chooses the concrete thin shell structure as the main architectural form.At the same time,ABAQUS was used to conduct modeling and numerical simulation analysis of free-form roof,the key component of the structure,to explore the mechanical properties of the structure under the action of roof load.The results show that the curved shell can transfer the stress and reduce the deflection.Increasing the thickness of the surface can effectively reduce the maximum stress of the whole structure and the maximum support reaction force of the bottom ring beam.
