It is an effective measure to reduce the loss of earthquake disasters through seismic appraisal of existing residential buildings and seismic reinforcement of houses that do not meet the appraisal requirements. At present, the prefabricated reinforcement method that is lightweight, fast, low-carbon, and reduces the impact on use has become the main development trend of reinforcement technology.

This paper takes a kind of comb-plate expansion joint as the research object, applies the structural dynamics analysis method and finite element analysis software for dynamic response analysis, and combines with miner fatigue cumulative damage theory for fatigue life estimation of the weak position of the expansion joint. Based on this, the results show that the panel and the welded seam are the vulnerable positions of the comb-plate expansion joint, and the welded seam is the most unfavorable position and suffers the most stress. The parts of the expansion joint show a linear growth trend with the increase in vehicle speed. The fatigue life at the panel is 24 million times, the life at the weld is 5.42 million times, and the weld is the earliest part to be damaged.

This study examined the effects of USP-C1 type modifier at 2%, 4%, 6%, and 8% dosage on the conventional and high temperature rheological properties of SBS-modified asphalt. From the results of the three index tests and Brinell rotational viscosity test, it can be seen that the USP modifier can considerably lower the viscosity of SBS modified asphalt and enhance its low temperature performance; from the results of the dynamic temperature scanning test, it can be seen that the USP modifier reduces the complex modulus and the rutting factor of SBS modified asphalt, which adversely affects its high temperature performance; from the results of the Multiple Stress Creep Recovery (MSCR) test, it is evident that the the addition of USP increased the cumulative strain response and irrecoverable creep flexibility of SBS modified asphalt.
