【摘要】：随着社会的发展,人们对于建筑的追求不再只局限于安全、舒适,更体现在美观、开放、节能等方面。钢结构高层建筑作为集众多优势于一身的建筑结构体系逐渐吸引人们眼球。新一类建筑体系的使用必将带来潜在的风险,保险作为转移风险,维持社会稳定的重要手段必须发挥应有的价值。针对钢结构建筑的建筑工程一切险产品存在着承保前风险分析不全面,评价结果精确性低等现象导致建一险产品在承保钢结构建筑项目时没有达到预期的效果。针对钢结构高层建筑特点设计针对此类建筑的建一险产品是至关重要的。本篇论文应用了工作分解法与依赖结构矩阵相结合方法分别从钢结构工程的施工工序及风险因子两个角度对钢结构高层建筑风险进行分析。风险评价过程中分析由于每一个工作包之间的相关性,导致风险会在工作包间进行传播,构建依赖结构矩阵(DSM)。通过分析风险传播网络与风险传播算法建立风险传播模型,利用可达矩阵计算方法求出项目存在的耦合模块,计算出更可靠的工程项目风险值并画出风险网络图将风险因素在工序之间的传播情况可视化。依据风险评价结果可以把风险及工序按照大小进行排序,划分工程项目风险等级。并有针对的制定承保方案。最后通过钢结构高层项目实例进行模型应用。
[Abstract]:With the development of society, the pursuit of architecture is no longer confined to safety and comfort, but also reflected in beauty, openness, energy saving and so on. Steel structure high-rise building as a collection of advantages in one building structure system gradually attracted people's attention. The use of a new type of building system will bring potential risks. Insurance as an important means to transfer risks and maintain social stability must play its due value. The pre-insurance risk analysis is not comprehensive and the evaluation result is not accurate enough for all the dangerous products of steel structure construction engineering, which leads to the failure of the construction of a dangerous product in underwriting the steel structure construction project. It is very important to design a dangerous product for this kind of building according to the characteristics of steel high-rise building. This paper applies the method of work decomposition and dependent structure matrix to analyze the risk of high-rise building in steel structure from the two aspects of construction procedure and risk factor of steel structure engineering. In the process of risk evaluation, it is analyzed that because of the correlation between each work package, the risk will be propagated between work packages, and the dependency structure matrix will be constructed. The risk propagation model is established by analyzing the risk propagation network and the risk propagation algorithm, and the coupling module of the project is obtained by using the reachability matrix calculation method. A more reliable project risk value is calculated and a risk network diagram is drawn to visualize the propagation of risk factors between processes. According to the risk evaluation results, the risk and process can be sorted according to the size of the project risk classification. And there are targeted insurance plans. Finally, the application of the model is carried out through the example of steel structure high-rise project.
