This paper presents the innovative use of hot-rolled thickness-tapered mill products, longitudinally profiled (LP) plates, for the seismic performance of bridge bents of single and portal framed piers. The study involves the inelastic cyclic testing and numerical analysis of tested beam-columns and portal frames in order to evaluate the effects of tapering ratios of LP plates, penetration of yielding, and number of locally buckled panels on their structural ductility. A structural design method is proposed for the portal frames having LP panels under cyclic loadings.

In this paper, structural performance of damaged SRC beam-columns with open-web type of batten steel plate after retrofitting was investigated. Three open-web type SRC beam-columns with bolt-connected batten steel plates were fabricated and tested under combined constant axial load and cyclic lateral load. At first, each beam-column was　cyclically loaded to the targeted displacement. After the first loading, the test columns were retrofitted and reloaded till large deformation or failure. The damaged portion of each column was retrofitted with the polymer cement mortar and epoxy resin was injected into the cracks. The measured stiffness of retrofitted columns varied between 71.4% and 85.5% of the initial one. And, test results also indicated that the column which experienced the larger displacement and higher axial load showed lower load carrying capacity, but the others showed approximately the same capacities as the initial columns. Numerical analysis was also conducted to explain the retrofitted columns. Analytical results predicted the experimental behavior fairly well, which verifies the validity of the analytical models in low axial load.

Influence Degree

The pressure hull is a very important for the overall performance of underwater vehicles, this paper investigates the structural performance of cylindrical pressure hull for underwater vehicles. Taking into account that there are much factors affect the performance of pressure hull, and these factors exists some coupling relationship between each other for pressure hull performance, so the orthogonal design method has been used in this paper, which can establish the representative test program. The ultimate strength of pressure hull is calculated with the finite element method. A design of experiments is performed to evaluate the effect of geometry parameters to the ultimate strength of the pressure hull. Through this study, the designers can clearly understand the influence degree of geometry parameters for pressure hull performance, which can provide reference for the structural design of cylindrical pressure hull.
