Loess Ribbed Composite Wall Structure System Risk Analysis

Multi-ribbed composite wall structure is a newly energy-saving, anti-seismic,assembled monolithic building structural system. According to the structural system,our team conducted a lot of theoretical and applied researches and obtained a greatbreakthrough. At present, the theory of its structural design theory is basically mature,and it’s time to come into the stage of promotion, moreover, it has been applied in manyloess areas which have many earthquakes and high intensity. However, as a new type ofstructural system, there are many uncertainty factors in the process of the promotion andapplication in loess areas, which affects the rapid development of the structural system,moreover the uncertainty risk factors haven’t been analyzed and studied. In thisconnection, this paper mainly focuses on the following content:(1)Providing a reference for construction of the structural system, which not onlyunder the full understanding of multi-ribbed slab structure characteristics and designingrequirements, but also under the site survey of project on construction technology andmethods in loess areas. And establishing the fine basis for professional recognition ofrisk factors of multi-ribbed composite wall structure system in loess areas.(2)Presenting the fit risk analysis methods, which based on the principle of fuzzymathematics and analytic hierarchy process, we establish the risk analysis model, whichestablishes the theoretical basis for risk analysis of multi-ribbed composite wallstructure system and also provides the reference method for the structure in further riskanalysis research.(3)Investigating and referring all aspects of the relevant experts, the main riskfactors, which are in the whole life cycle of multi-ribbed composite wall structuresystem in loess areas, are divided into decision-making stage, implementation stage andusage stage to identify, and we can use the established risk analysis model to conductcomprehensive analysis, then we can concluded that decision-making stage and implementation stage are more bigger than others. Thereinto, related policies, socialrecognition, several concrete wall design and complex construction process risk factorstakes up a larger proportion, which are the key considerations to the assessment andcontrol, and the analysis results can provide risk management for multi-ribbedcomposite wall structure system in loess areas, so as to reduce the risk and promote thedevelopment and application of the structural system.
