Abstract ：
The supporting hotel of the National Convention Center Phase II employed a novel type of transfer joint for connecting steel and reinforced concrete structures, and studied geometrically regular and symmetric transfer joint. However, the mechanical properties of irregular, asymmetric joints within this hotel structure have not yet been examined. A representative asymmetric beamcolumn transfer joint was selected, and its failure process and mechanical performance were investigated based on a finite element model. The simulation results indicate that the construction form of the transfer joint can be applied to asymmetric beam-column joints, achieving the design goal of yielding in the upper part first.

Abstract ：
Pneumatically supported membrane structures belong to wind-sensitive structures, and the on-site measured wind pressure data is a very valuable and intuitive data source for pneumatic membrane structures. However, the acquisition of wind pressure data is difficult, costly, and there is very little research on the processing of wind pressure data for pneumatic membrane structures with long duration. In this paper, all wind pressure measurement points on-site of the pneumatic membrane structure were taken, and based on the characteristics of the measured wind pressure data, the data was preprocessed by dividing the data into abrupt change points to remove baseline shifts caused by abrupt changes. The results show that the algorithm proposed in this paper is efficient, and provides flexibility in dividing abrupt change points, laying a foundation for further extracting useful information from the data. This algorithm can also be applied to data processing with similar characteristics in other applications.

Abstract ：
Form-finding is crucial for the design of typical cable net structures. Based on the original basic force density method, a modified force density method utilizing the concept of relation matrix is proposed in this paper. The modified method realizes the establishment of a clear correspondence between members and nodes of cable net structures. On the basis of the relation matrix, the find function is introduced, and the calculation formula of the modified branch-node matrix is derived. Meanwhile, the corresponding analysis steps and calculation process are given. The modified method is verified by the analysis of representative structural forms. The results show that for the saddle-shaped orthogonal cable net structure, the outcomes obtained from the modified force density method highly agree with the theoretical values, providing preliminary verification of the method's effectiveness. For single-layer spoke cable net structures, the relative error between the results calculated by the modified force density method and the numerical solution is approximately 5 %. The results of both methods are relatively consistent, and the relative error varies in relation to the ratio of inner ring cable force density to radial cable force density. For circular single-layer crossed cable net structure without inner ring, the results of the modified force density method are very close to the numerical solution. The maximum relative error between the two is 6.95 %, and the accuracy is higher than that of the nonlinear finite element method. The outcome of this research demonstrates the accuracy of the modified force density method and its effective application in the form-finding of actual cable net structures.

Abstract ：
The cable net and membrane of the air-supported membrane structure transmits the load through mutual extrusion, and the contact interaction between the cable net and membrane should be considered in the initial morphological analysis stage. In this paper, a scale model was designed according to a large-span air-supported membrane structure engineering project, and the shape and force of the structure were measured. At the same time, a finite element model of cable-membrane contact was established, and its interaction behavior was regarded as a combined contact state and sliding contact state. The results show that the influence of different contact state analyses on the prestress of the cable net is obvious, and the influence of the sliding contact between the cable and the membrane should be considered in the design of the membrane structure.
