“…Thus, most studies used lateral displacement or drift ratio to assess the behavior of the designed bridge subject to different loadings, while other studies used time dependent reliability analysis. Various applications in this area [146][147][148][149][150][151][152][153][154][155] are summarized in Table A11.…”

“…They evaluated the solutions of both the entropy and TOPSIS methods for performance analysis. Sharma et al [152] developed a probabilistic demand model to design the desired behavior of reinforced columns under different vehicle impact scenarios. The PB fragility estimates can be used to assess the likelihood of a specified performance of an RC column in a given impact scenario.…”

“…When one source of the uncertainty is far greater, as is the case of natural-hazard loads, the response is separated from the hazard (uncouple analysis), which is the basis for the fragility analysis [142,149,152]. Another type of analysis that lies between the preceding two types (partially coupled analysis) has been proposed [105].…”

“…Physical approaches based on SDOF and MDOF systems have been used to model displacement with respect to velocity and acceleration, which are the fundamental principles found in structural and seismic studies [138]. Thus, different FE models are developed to aid in assessing the geometric design subject to stress analysis, where software such as DRAIN-2DX and LS-DYNA are used in various studies [152]. Another popular analytical tool adopted in structural engineering applications is the pushover analysis.…”

Traditional design approaches in civil engineering mainly focus on codes/guidelines related to building an infrastructure, while performance-based analysis (PBA), an emerging new reality around the world, focuses on the performance of the end product. Professional organizations, academicians, and the industry have made significant contributions in formulating PBA in various civil engineering fields, where practical guidelines and principles have been adopted in infrastructure analysis. This paper presents a critical review of PBA applications in three civil engineering fields: transportation, environmental, and structural engineering. The applications are grouped into a wide array of civil engineering areas, including highway transportation, pavement design and management, air transportation, water-structures design and operation, landfill design, building architectural design for evacuation, urban energy design, building earthquake-based design, building wind-based design, and bridge design and management. A total of 187 publications on PBA were reviewed and details on 122 application papers (from 23 countries/regions) are presented. The review consists of vertical and horizontal scans of PBA applications. In the vertical scan, the applications in each civil engineering area are summarized in tabular format that shows the system element modeled, analysis objective, performance criteria, analytical tool, and specifications/codes. The horizontal scan (discussion and lessons learned) addresses the following aspects of PBA: (1) the wide array of analytical tools used, (2) the broad functional and process-related areas, (3) the advantages, challenges, and opportunities, and (4) potential future applications. It is hoped that the state-of-the-art review presented in this paper will help researchers/practitioners quickly find useful information about PBA and promote its development in their respective fields.

The increasing occurrence of vehicle-pier collision accidents has significant influences on the safety of bridge structures. In order to study the impact behavior of bridge piers, a vehicle-double-pier collision numerical model was developed by LS-DYNA. Nonlinear material constitutive laws considering the strain-rate effect were used. The reliability of numerical analyses was validated. Parametric studies were carried out to investigate the effects of impact velocity, impact mass, and concrete and steel strength on the impact behaviors of piers and the impact forces. The relationship between failure modes of the impacted piers and impact energy was analyzed. Based on the numerical analysis results, the current impact design provisions of AASHTO, Eurocode, and JTG D60 were found to be unconservative, which could result in that piers designed with the current standard codes were vulnerable to the large impact energy. The recommended value of equivalent static force in the current standards is unreasonable.

This study analyzes the behavior of reinforced concrete (RC) members impacted by vehicles or trains by reviewing existing experimental and numerical work. RC structures are susceptible to such collisions, which can cause structural failure or collapse. The damage response depends on the energy transferred during impact, ranging from cosmetic effects to full structural failure. To properly characterize damage, indices are defined considering concrete and steel strain rates during and after plastic deformation. Concrete spalling is also discussed as an indicator of localized or global failure severity. Experimental results from other studies are presented and compared to theoretical models. The latest provisions for incorporating strain rate sensitivity into material models based on various standards are reviewed. This analysis aims to provide insights for better assessing the reliability of RC members after impacts. Understanding reliability is important for evaluating the safety of damaged structures and mitigating risks. The findings can help practitioners evaluate damaged structures and guide future design to avoid severe outcomes from vehicle and train collisions onto critical infrastructure.
