This paper investigates the in-plane seismic behaviour of hinged steel frames that are enhanced with masonry columns and/or infilled walls. First, eight half-scaled hinged steel frame specimens were constructed according to the realistic structural system of Bund 18, which is a historical building in Shanghai, China. Then, cyclic loads were exerted on these frames. The test results indicated that the seismic behaviours of the hinged steel frames can be significantly improved with the use of masonry columns and/or infilled masonry walls as well as with proper strengthening due to carbon fibre-reinforced polymer (CFRP) sheets. A simplified model was developed to simulate the seismic behaviours of these frames. In this model, infilled walls and CFRP sheets were replaced by diagonal struts, and the steel members and their surrounding elements were treated as composite members. Finally, this model was verified by experimental results. [ABSTRACT FROM AUTHOR]

(eds.), Current Advancements in Marine and Coastal Research for Technological and Sociological Applications. Journal of Coastal Research, Special Issue No. 107, pp. 341-346. Coconut Creek (Florida), ISSN 0749-0208. The financial development of coastal port cities plays a crucial role in their economic development. This paper uses 18 indicators of 16 Chinese port cities along the "New Maritime Silk Road" in the 2018 China Statistical Yearbook to reflect the level of financial development and financial development environment, AHP is used to determine the weight of each indicator, cluster analysis is used to classify the cities according to the financial development level, and then principal component analysis is used to analyze the indicators, so as to get the score ranking of each city's financial development level, find out the reasons for the differences in financial development of port cities. The result shows that the financial industry strength and development speed of Shanghai, Guangzhou and Shenzhen are in the forefront due to historical accumulation factors and long-term national policy support. Cluster analysis further proves that the financial development of each port city has significant differences, and the influencing factors also have regional differences, among which the economic development level, economic growth level and the development of banking and insurance industry have a greater impact on the financial development of the city.
