Flat plate floor systems are most often constructed in residential or mixed-use buildings for a variety of reasons such as shortening the construction time, reducing the floor height and achieving spatial flexibility. Additionally, flat plate floor systems have the largest volume among the structural members, so these systems have the largest influence on determining the carbon dioxide (CO2) emissions and costs incurred in the building construction and design stages. To analyze how CO2 emissions and amount of building materials in the floor system are affected by design parameters that can be considered in design and construction stages, a sustainable design model that minimizes CO2 emissions and construction costs of the flat plate floor system is developed. The developed technique was applied to design of flat plate floors with 126 different dimensions to analyze the effect of the design parameters on costs and CO2 emissions. Additionally, the performance of the proposed method was evaluated by applying it to design of a 47-story mixed-use building. The results indicates that active design parameters that determined the environmental impact and cost of flat plates were the yield strength of rebar, rebar diameter, slab thickness, and the compressive strength of concrete.

设计参数的变化对住宅或混合用途建筑平板地板系统可持续设计模型的影响

平板地板系统最经常在住宅或混合用途建筑物中建造,其原因有很多,例如缩短了施工时间,降低了地板高度并获得了空间灵活性。另外,平板地板系统在结构构件中具有最大的体积,因此这些系统对确定二氧化碳(CO 2)排放和建筑物建造和设计阶段中产生的成本具有最大的影响。为了分析地板系统中的CO 2排放和建筑材料的量如何受到设计和施工阶段可以考虑的设计参数的影响,这是一个可持续的设计模型,可最大程度地减少CO 2开发了平板地板系统的排放和建筑成本。将开发的技术应用于具有126种不同尺寸的平板地板的设计中,以分析设计参数对成本和CO 2排放的影响。此外,通过将其应用于47层混合用途建筑的设计中,对所提出方法的性能进行了评估。结果表明,确定平板对环境的影响和成本的有效设计参数包括钢筋的屈服强度,钢筋直径,板厚和混凝土的抗压强度。
