Vibration control of a Plan irregular RC framed structure under seismic excitations with the help of TMD along with bracings
Abstract: The study of dynamic behavior of high-rise structures is immensely important as the dynamic response of the structures due to natural forces like seismic forces, wind forces etc. may result in structural failure. An unsymmetrically located shear wall or similar kind of stiff element may cause the structure to have plan irregularity. Such type of plan irregularity in high rise structure can induce the torsional displacements in the structure subjected …

A Threshold-Weighted Mathematical Fusion Model for Epidemic Outbreak Prediction Using SEIR Residual Dynamics and Cloud-Based Machine Learning
Abstract: Accurate prediction of epidemic outbreaks is critical for effective public health management, resource planning, early warning generation, and timely intervention by municipal authorities. Traditional compartmental models such as Susceptible–Exposed–Infectious–Recovered (SEIR) offer valuable epidemiological insights and mathematical interpretability; however, they may not adequately capture the complex nonlinear relationships present in real-world urban health systems. Conversely, data-driven machine learning techniques can identify hidden patterns in large datasets but often lack epidemiological structure …

Seismic Analysis of Symmetrical and Unsymmetrical Multistory Building with Shear Wall and Hybrid Shear Wall
Abstract: Shear walls are structural systems which provide stability to structures from lateral loads like wind, seismic load. Shear walls are added to the building interior to provide more strength and stiffness to the building when the exterior walls cannot provide enough strength and stiffness. It is necessary to provide these shear walls when the tolerable span width ratio for the floor or roof diaphragm is exceeded. Shear walls are mainly …

Comparative Study of Seismic Performance of Multistory Symmetrical RC Frame Structure with and Without Dampers
Abstract: This paper investigates the influence of friction dampers on the nonlinear seismic performance of multistory structure. The operational mechanism of these devices is that a large amount of energy inputting to the structure could be absorbed and the displacement of the structure is reduced. For this purpose, four types of frames are investigated with dampers at different locations. Three types of natural time histories are used for the nonlinear seismic …

Effect of Strong Column Weak Beam Concept on Seismic Capacity of Buildings of Varying Heights: A Review
Abstract: The strong-column-weak-beam (SCWB) layout philosophy in which plastic deformation is authorized to arise most effective with inside the beams whilst the columns continue to be basically elastic is broadly followed in seismic layout codes for metallic second frames. Under this yield mechanism, the seismic strength is dissipated ordinarily with the aid of using the plastic hinges with inside the beams and on the column bases. The relative plastic flexural capacities …

Seismic Analysis of Elevated Intze Type Water Tank
Abstract: As known from previous occurrences, Elevated water tanks were heavily damaged or collapsed during earthquakes. This might be due to lack of knowledge about seismic behaviour of water tank or improper geometrical selection of staging patterns. The staging plays critical role in design of water tanks as in water tanks large mass is supported by slender staging. The main objective of this study is to understand the seismic behaviour of …

X Plate Damper for Seismic Response Control of the Building
Abstract: The building system causes excessive vibrations during the seismic event which can lead to the complete collapse of a building, bridges etc. resulting in damage to the structure. Hence, the safety of the structures is essential to keep the building functional during and after the effects of the earthquake. To overcome these damages, additional energy dissipation systems are considered for the seismic protection of the building. The aim of the …

Analysis of Elevated Liquid Storage Tank on Sloping Ground with Variable Heights
Abstract: Past earthquake events have shown that even well-designed elevated water tanks can suffer severe damage or collapse. Much of this damage occurs due to a limited understanding of the behavior and appropriate selection of supporting systems during the design process. With a large mass concentrated at the top of slender supports, these tanks are especially vulnerable to horizontal seismic forces. Therefore, it is crucial to evaluate the strength and performance …
