Fragility curves are fundamental tools in seismic risk assessments, providing insights into the vulnerability of structures to earthquake-induced damages. These curves, which plot probability a structure reaching or exceeding various damage states against earthquake intensity, critical for developing effective modification strategies. This review aims present characteristics between building- and site-specific fragility incorporate detailed local characteristics, generic that apply broader, more generalized parameters. We utilize PRISMA (Preferred Reporting Items Systematic Reviews Meta-Analyses) methodology systematically literature address key research questions about methodological differences, applications, implications these curve types assessing risks. The methods involved comprehensive search combination existing studies on topic, focusing how developed applied real-world scenarios. results from this show while precise, require extensive data therefore complex costly develop. In contrast, though less accurate, offer cost-effective solution preliminary assessments over large areas. conclusions drawn suggest each type has its merits, choice should be guided by specific requirements assessment task, including available resources need precision estimations.

Response of Corroded Steel Pipeline Without and with CFRP Reinforcement to Reverse Fault Movement

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(23), P. 10896 - 10896

Corroded steel pipelines are particularly vulnerable to failure due ground movement, which highlights the need improve their seismic resistance through reinforcement methods. This paper establishes a three-dimensional finite element model of corroded pipeline subjected reverse fault, considers effects corrosion position and depth, winding thickness, length carbon fiber-reinforced polymer (CFRP), investigate stress, strain, elliptic deformation, modes before after CFRP reinforcement. Results indicate that main mode intact crossing fault is local buckling. Corrosion intensifies response cross-fault pipeline, accelerates its occurrence, promotes transformation from single multiple modes. For reinforcement, an increase in thickness can effectively inhibit growth pipeline’s compressive thus reducing buckling potential. Each additional layer further enhance overall but at decreasing rate. Similarly, longer improves though effectiveness per meter decreases. Therefore, it recommended on should be optimized obtain best reasonable cost.
