“…Some recent studies have looked closely at the computa tion and applications of the BHI, investigated the BHI's sensitiv ity to cost and element condition (10), and suggested new methods for computing the state weights (4-6). Rens et al presented the use of element weights for condition index computation on a nonbridge structure (sheet piles) (12). To evaluate the trends over time of BHIs computed with the Shepard and Johnson (3) equations, Jiang and Rens (4,5) and Jiang (6) used bridge data from Denver, Colorado.…”

“…However, when the bridge deteriorates with age, its economic value depreciates. To assess the statistical distribution of bridges with respect to their BHI, the con dition ranges and implied bridge maintenance or repair actions were reviewed, as explained by Jiang (6) and Rens et al (12). Although the BHI was implied in those two studies to be used in decision making on maintenance, repair, or replacement actions, such use of BHI is not typical.…”

The AASHTO Pontis bridge management system has been used to support network-level and project-level decision making on the condition and functional obsolescence of bridges. State departments of transportation often develop bridge inspection data collection methods, deterioration models, cost models, and other preservation analysis capabilities to comply with the requirements of the federal Government Accounting Standards Board. The bridge health index (BHI) in the Pontis bridge management system has been used in the evaluation of the condition of bridges and elements at the project and network levels. This paper investigates three issues in the computation of the BHI: the effects of using linear and nonlinear scales for the condition state weights when computing the element health index (EHI); the application of amplification weights to EHI values to emphasize bridge elements in bad condition; and the development of element weights based on element replacement costs, element long-term costs, element vulnerability to hazard risks, and a combination of these measures. Historical condition data from element-based inspection were used to evaluate these effects at the network level.

Pipe-sheet combination structure is a novel form of wharf structure, which utilizes steel pipe piles with better performance as the main stress components to withstand lateral pressures such as water pressure and earth pressure, and low-cost steel sheet piles as the linking structure to form a pipe-sheet combination wall, which to a certain extent can take into account both the performance and the cost issues, but whether the pipe-sheet combination structure can be adapted to the design and use of the large-scale berths of the wharf under the deep-water environment has always been a controversial issue in the engineering field. However, it has been controversial in the engineering community. Therefore, it is necessary to analyze and research more deeply the actual force situation of the pipe-sheet combination structure and the applicable calculation method. In this paper, based on the field measurement data, the active earth pressure calculation of the back side of the pipe-sheet composite pile is compared and analyzed, and the results show that the earth pressure calculation formulas used in China and the United States for the sheet pile structure are much closer to the actual results compared to the calculation method of the Japanese specification in the calculation of the earth pressure of the back side of the pipe-sheet composite structure; the numerical simulation can be used to set up the pipe-sheet composite pile structure into an equivalent cross-section of the sheet pile module, which can effectively avoid the data of the sheet pile module, and can also be used in the numerical simulation. When numerical simulation is used, the pipe-sheet composite structure can be set up as a plate pile module with equivalent cross-section, which can effectively avoid the problems of aberration and stress concentration in the data calculation, and the calculation results can better respond to the actual stress situation in the field.

U-Shaped Steel Sheet Piles (USSSP) have buckling and bending problems during construction. In this research, the structural measure of stiffened plates applied along the longitudinal direction of USSSP is analyzed and proposed. A theoretical calculation method of stiffening effect is proposed based on the dynamic correlation coefficient method and the formula for the critical buckling load of locally stiffened USSSP is derived. A parametric analysis of the number, width, and arrangement scheme of the stiffened plates on the USSSP with different lengths is examined. The empirical formula derived for the total stiffening area and the critical load of the axial compression members of the USSSP is compared with practical results from an engineering case study. The results show a quadratic function under the condition of arranging the different number of stiffened plates at equal intervals, which is accurate in deriving the critical load values USSSP after local stiffening, and provide a theoretical basis for the optimization design of local reinforcement of USSSP axial compression members in engineering projects.
