SEISMIC PERFORMANCE ASSESSMENT OF A BASE ISOLATED REINFORCED CONCRETE BRIDGE

Bridges in seismically active regions require rigorous assessment to ensure resilience. This paper presents a comprehensive structural evaluation of a 1.26-km‑long base‑isolated reinforced concrete bridge in the Philippines, designed to accommodate increasing traffic demands while maintaining integrity under seismic lo...

Seismic Performance Assessment of Reinforced Concrete Buildings Using Nonlinear Static Pushover Analysis

Seismic assessment of reinforced-concrete (RC) buildings requires understanding behavior beyond the elastic range. Linear analysis cannot reveal yielding or capacity loss; nonlinear dynamic analysis is costly, and few studies report pushover output for a regular frame and an existing building. This study applies nonlin...

Comparative Nonlinear Seismic Response of Fixed-Base and Lead-Rubber-Isolated Reinforced Concrete Building Systems

This study examines how lead-rubber bearing (LRB) isolation changes the seismic response of a ten-story reinforced-concrete building using matched fixed-base and isolated models. Three-dimensional ETABS models were analyzed using nonlinear direct integration under the EQ-X component of the 1999 Kocaeli earthquake recor...

Evaluating the Seismic Performance of Circular Concrete-Encased Steel Bridge Columns for High Seismicity Regions

This research evaluates the seismic resilience of lifeline bridge columns in Vancouver, British Columbia, by comparing traditional reinforced concrete (RC) columns with an equivalent circular concrete-encased steel (CES) system. Designed to meet the stringent performance-based requirements of CSA S6-25 and the BC Minis...

Numerical Analysis and Design of Short Reinforced Concrete Columns Subjected to Axial Load and Biaxial Bending Using Abaqus

Short reinforced concrete (RC) columns in multistory structures are frequently subjected to combined axial load and biaxial bending arising from wind, seismic actions, and construction eccentricities. Accurate prediction of their nonlinear response remains challenging due to complex stress interactions and limitatio...

Enhancing the seismic performance of plan irregular L-shaped reinforced concrete buildings using steel bracing systems

Seismic retrofitting of existing reinforced concrete (RC) buildings is often required because of deficiencies in their original design, changes in seismic provisions, or increased functional demands. This study evaluates the effectiveness of steel bracing for improving the seismic performance of a ten-story, plan-irreg...
