Optimization of Shear Wall Placement to Improve Seismic Performance of High-Rise Buildings Using Pushover Analysis

High-rise reinforced concrete buildings are susceptible to seismic forces due to their slenderness and flexibility, necessitating effective lateral load-resisting systems. This study investigates the optimal placement of shear walls to enhance seismic performance. A seven-story symmetrical building model was developed...

EFFECT OF SHEAR WALL AREA RATIO ON THE STRUCTURAL PERFORMANCE OF MID-RISE AND HIGH-RISE RC BUILDINGS

The increasing demand for multi-storey reinforced concrete (RC) buildings has emphasized the need for efficient lateral load-resisting systems capable of withstanding seismic and wind-induced forces. Shear walls are widely recognized as one of the most effective structural components for controlling lateral displacemen...

Assessment of the stress–strain state of a two-span reinforced concrete bridge subjected to real earthquake records

This paper investigates the seismic response and stress-strain state of a two-span reinforced concrete highway bridge subjected to real earthquake records using advanced numerical modeling. A three-dimensional model of a 48 m long bridge was developed considering structural characteristics, support conditions, and soil...

Seismic Retrofitting of Residential Frame with Outrigger Rocking Wall

Existing frame structures are known to exhibit shear-type deformation attributed to the flexural behavior of components such as columns and beams. To improve their strength and stiffness, this paper intends to utilize the axial capacity of columns to contribute to the overall flexural resistance and proposes a novel...

Seismic Performance of a Frame–Core Tube Building with Nonlinear Viscous Damper-Equipped Coupling Beams

Nonlinear velocity dampers (NVDs) embedded in coupling beams may enhance the seismic performance of frame–core tube structures by dissipating energy and limiting structural damage. This study evaluates the seismic performance of a 20-story reinforced concrete (RC) frame–core tube building incorporating NVD-equipped cou...
