Abstract:
This research investigates the seismic performance of overhead water tanks, focusing on the comparative effectiveness of two seismic load control mechanisms: dampers and staging, under varying water levels. Overhead water tanks are critical infrastructure in urban and industrial settings, and their seismic stability is essential to ensure safety and functionality during earthquakes. However, the dynamic behavior of these tanks under seismic loads can vary significantly based on water levels and the structural interventions applied. In this study, a detailed parametric analysis was conducted using numerical simulations to assess the impact of dampers and staging in reducing seismic forces on overhead water tanks. Various water levels were considered, as the presence of water inside the tank can influence its natural frequency, damping, and overall response during an earthquake. Two distinct approaches damping systems and staging arrangements were modeled and analyzed for their effectiveness in mitigating seismic vibrations and improving the structural integrity of the tank. The results showed that both dampers and staging contribute to enhanced seismic resistance, with significant differences in performance across different water levels. Dampers, particularly viscous and friction-based types, were found to reduce the amplitude of vibrations effectively. Staging, on the other hand, provided added stability by distributing seismic forces more evenly across the structure. Structural modeling and seismic analysis of overhead water tanks were performed using ETABS software. The objective was to assess and compare the seismic behavior of tanks with varying design configurations and service conditions. A standard reinforced concrete tank model was developed, incorporating key components such as the container, staging system (where applicable), and a fixed-base foundation. Staging is identified as the most effective seismic control strategy for overhead water tanks, significantly reducing critical response parameters like displacement, drift, bending moment, and shear force. While damper systems offer moderate control, they also increase axial force, torsion, and base shear, potentially affecting structural integrity.
