“…Small variations of some uncertain factors such as load may affect the mechanical properties of structure significantly just because it has a bad topology configuration and an inappropriate prestress. For example, the unreasonable structure members arrangement of Malaysian Abidin Stadium leaded to a sudden collapse just under normal loads [1]. To get better topology configuration and prestress through robustness based structure design is an effective way to solve the problem of disproportionate damage issues caused by uncertainty [2].…”

This article finds out the topology configuration and prestress which have the optimal robustness of cable-supported shells as follows. The structure robustness evaluation index is assessed by the H 2 norm of system transfer function. The robustness based structure design is transformed into continuum topology optimization by using SIMP material model. The improved Big bang-Big crunch (BB-BC) method employing pseudo-gradient factor is used to get the optimal solution of the topology configuration and prestress joint optimization. Examples show that the improved BB-BC method can solve the joint optimization problems effectively. Topology configuration of the cable-supported shell with a single strut varies with the initial prestress conditions reasonably. The comparison of the joint optimized topology configurations of cable-supported shells with different struts shows that the distribution of material of the shell with five struts is more uniform than that of the shell with a single strut.

Building information modeling (BIM) can be recognized as the most promising technology that was introduced to the construction sector in the recent past. The current BIM-based safety risk assessment methods ignore data uncertainty. Hence, this study integrates BIM with fuzzy set theory for safety risk prediction. A Fuzzy Inference System (FIS) was developed based on the causality of safety incidents. The FIS extracts construction project data from BIM models while automatically assessing each potential safety hazard and project’s total risk. The proposed method was demonstrated by using a building project in which the safety risk was predicted as low. Safety records of the above project revealed that no safety incidents were recorded in this project. The proposed method can indicate the safety risks level at various stages of a construction project and help to enhance the safety of construction workers on a construction site.
