The wood arch bridge has good seismic performance, and the “wood weaving” of its arch system is closely related. Wood weaving has the isolation function similar to that of rubber bearing isolation layer under earthquake, which is the key to ensuring good isolation performance of wood arch bridges. However, it is difficult to measure the seismic performance of the “wood woven” structure of the wooden arch bridge, which leads to its limited application. In order to solve this problem, building information model (BIM) technology is introduced into this field, and the application of BIM technology in the seismic performance of “wood woven” structures of wooden arch bridges needs research. First, the design principle of “wood weaving” is described, and then the seismic principle of “wood weaving” is analyzed. Finally, from the perspective of the structural strength index, the seismic performance of the wooden arch bridge “wooden woven” structure is analyzed in depth with BIM technology in order to provide some help for understanding the seismic performance of the wooden arch bridge “wooden woven” structure and promoting the effective application of wooden arch bridge.

“…𝑁 𝑐 , 𝑁 𝑞 , 𝑁 𝑟 are calculated using Eqs. ( 4), ( 5) and (6). After the relationship between 𝑃 𝑢 and the two variables is analyzed, Terzaghi's ultimate bearing capacity equation is kept unchanged for comparison with the theoretical equation.…”

“…Coral reef sandy soil has so far not been listed as a category in the Code for Investigation of Geotechnical Engineering in China, and with respect to the bearing capacity of the coral reef sandy soil foundation [5], relatively few experimental studies have been conducted by domestic and foreign scholars. Zhu [6] et al analyzed the bearing capacity characteristics of the coral sand foundation through field tests and pointed out that the deformation modulus of the foundation soil is positively correlated with the blow count N10 of the light dynamic penetration test. The test results of Wang [7] et al showed that the bearing capacity and deformation modulus of artificially filled coral soil foundations were significantly higher than those of naturally formed reef flat facies and sandbank foundations and that the resilient modulus of coral soil increased with the increase of the degree of compaction; Yang et al [8] using the least square method proved the correlativity between the eigenvalue of foundation bearing capacity and the blow count N of standard penetration test (SPT) and the blow count N63.5 of heavy dynamic penetration test with modified eigenvalue of foundation bearing capacity; Li et al [9] conducted a plate loading model test study on coral sand foundation and found that the settlement of coral sand was 50 % to 67 % of the value calculated with the empirical equation.…”

The mechanical characteristics of coral reef sandy soil is significantly different from the sand and clay soils. Currently, Terzaghi's bearing capacity equation is still commonly applied to evaluate the bearing capacity of coral reef, while the calculation result is not consistent with the actual condition. Based on a port project in east Africa, plate loading test of the coral reef sandy soil has been conducted and the P-S curves are obtained, and the bearing capacity values obtained from the plate loading test results are compared with the calculated results based on the Terzaghi's bearing capacity equation. According to multiple linear regression and the optimal regression equation selected by the significance test, the modified Terzaghi foundation equation of bearing capacity in coral reef sandy soil area is proposed, and the modified Terzaghi foundation equation has important reference value for the calculating of the bearing capacity of the coral reef sandy soil foundations.

In order to improve the safety performance of supertall buildings under earthquake, a seismic performance analysis method of double lines of supertall buildings based on a response surface optimization algorithm is proposed. Firstly, the structural performance indexes of super high-rise buildings are selected, and on this basis, the material constitutive model is constructed by the structural elastic-plastic analysis method to complete the seismic design of the first line of defense. Then, the response surface method is used to optimize the material constitutive model and complete the seismic design of the second line. Finally, the anticollapse limit state analysis method is used to determine the seismic performance of the double line of super high-rise building structures. The experimental results show that the proposed analysis method has high seismic performance, and the axial compression ratio of wall and column is always stable, in which the column is always at about 0.5 and the wall is always at about 0.26, which lays a foundation for the safety performance of super high-rise building structures under earthquake.
