In order to ensure the successful implementation of the old industrial building recycling project, all participants must share the project risks reasonably. This paper takes the project of old industrial building recycling as the research object. Firstly, the Delphi method is adopted to identify the project risk. Based on the incomplete contract theory, the risk is clearly divided into the contracting stage and the risk of the performance stage. Secondly, based on participant satisfaction, build index system of risk sharing, using C-OWA operator for risk sharing weighting, avoid the ill effects of the expert subjective preferences, under TOPSIS and UT theory, form a sharing mode that is complete, reasonably define the responsibility attribution of risks and determine the optimal sharing proportion of Shared risks. Finally, the model is applied to a creative industrial park project transformed from a steel mill in Shanxi province to prove the rationality of the model, and provide reference for the formulation of risk sharing scheme of China's old industrial building recycling project.

The source depth was 10 km. This earthquake killed 17 people and injured 285 people. The earthquake also caused huge property losses. Most of the casualties of the earthquake were caused by the collapse and damage of the buildings. The near field strong ground motion was the direct reason which caused the collapse of the building. The collapse of the buildings was greatly related to the amplitude and frequency of circulation of ground motion. The seismic response of system accumulated damage under cyclic load depends not only on the maximum amplitude of motion but also on the duration of motion. Many researchers suggest that the effective number of ground motion cycles is more reflective of seismic damage than the duration. The destructive ability of seismic ground motion depends on the amplitude of the movement and the number of cycles. In the geotechnical earthquake engineering, the number of motion cycles is the most important. Many researchers believe that the number of motion cycles is also an important factor in structural seismic design and damage assessment. Because the strength, stiffness and energy dissipation of the structure decreases with the increase of the load cycle, the amplitude itself is not sufficient to evaluate the seismic performance of the structure. In this paper, the spatial distribution characteristics of the damage index of Hualian earthquake is analyzed, and the correlation between the damage index and seismic intensity is analyzed.

The amplification effects of three ideal simple basin models, “square” shape, “inverted convex” shape and “curved” shape, were studied by using the finite element numerical simulation method of decoupled nearfield wave combined with transmission boundary. The results show that: 1. Two kinds of basin models, “square” and “inverted convex”, show different rules of seismic response of basin position along with the depth of basin: the square basin model shows similar characteristics to the existing site response, while the calculation results of inverted convex basin model are more fit our existing basin knowledge. Therefore, it is not appropriate to study the amplification effect of basin earthquake ground motion only by using simple “square” basin model. 2. The seismic response of a more realistic \"curved-edge\" basin model is studied. The calculation results of the symmetric model show good regularity. A relatively large seismic response occurs in the center of the basin, which reflects the role of the “focusing effect” of the basin. The asymmetric basin model is located in the center of the basin and at the edge of the basin. Greater ground motion responses have been observed on both sides of the basin, even on the steeper edge of the basin, which is related to the “edge effect” of the basin; with the softening of the medium in the basin, the ground motion responses of the site in the basin gradually increase; with the increase of the stratification of the medium in the basin, the ground motion responses of the basin are larger. On the whole, the seismic response also tends to increase gradually, but there are also large differences in some locations of the basin, which reflects the complexity of the amplification effect of the seismic basin.
