建筑室内环境空间结构稳定性评估仿真研究

建筑结构稳定性是影响建筑结构安全的主要因素之一,而建筑空间结构是影响建筑室内环境空间结构稳定性的主要因素,为此提出建筑室内环境空间结构特征稳定性评估方法。分别给出不同建筑室内环境空间结构的抗倒塌能力指标,即承载能力指标、建筑内空间结构延性指标和建筑影响系数指标,并计算不同载荷作用下抗倒塌能力指标的权值,在此基础上求得建筑结构抗震能力指数,将其与建筑物结构楼层的抗倒塌能力指标相结合,得到建筑室内环境空间结构稳定性评估结果。仿真结果表明,所提方法对于发展我国建筑室内环境空间结构特征稳定性评估具体十分重要的意义。

Simulation Study on Stability Evaluation of Spatial Structure of Building Interior Environment

The stability of building structure is one of the main factors of influencing the safety of building structure,and the spatial structure is the main factor of influencing the stability of indoor environmental spatial structure.Therefore,a method to evaluate the stability of spatial structure feature in building indoor environment was put forward.The indexes of anti-collapse capacity of different indoor environmental spatial structures were given,including the bearing capacity index,the ductility index of spatial structure and the building influence coefficient index of spatial structure.Meanwhile,the weight values of anti-collapse capability index under different loads were calculated.On this basis,the anti-seismic capacity index of building structure was obtained,which was combined with the anti-collapse capability index of building structure to get the evaluation result of the stability of spatial structure of building indoor environment.Simulation results show that the proposed method has great significance for developing the stability assessment of indoor environmental structure feature.
