Soil liquefaction vulnerability assessment of Sylhet city based on SPT value
Abstract: Bangladesh is an earthquake-prone country due to its geographic location. Sylhet, a divisional city, is situated in Zone IV, the most seismically active area in the country, according to the Bangladesh National Building Code (BNBC). A major earthquake can cause devastating effects in the subsurface, such as liquefaction, landslides resulting from a reduction of soil shear resistance. In this study, liquefaction potentiality of soil in Ward No. 9 of Sylhet …

“FORCE-DISPLACEMENT TRADE OFF” OF RCC BUILDING LOCATED AT VARIOUS SEISMIC ZONES AND SITE CONDITION ADOPTING TIME-HISTORY ANALYSIS
Abstract: Earthquake-resistant or aseismic design are considered to protect buildings to some or greater extent from earthquakes. The force-displacement trade off of structures located in various seismic zones are different in nature depending on intensity of earthquake. No structure can be fully immune to damage from earthquake, the vulnerability can be reduced for safety and durability. The force-displacement behavior of a particular structure can be modified to withstand seismic occurrence preventing …

EFFECT OF RE-ENTRANT CORNER IRREGULARITY IN A STRUCTURE
Abstract: AbstractIrregularities are not avoidable in construction of a building. Building Structures are almost irregular, as ideal perfect regularity very rarely occurs now days. As far as buildings structures are concerned , for practical use , Indian seismic code divides irregularity in structure which are in plan irregularity and in elevation irregularity, but it had been found and realized that irregularity in structures is the result of a combination of both …

Seismic Risk Assessment of Soft-Story Buildings Using a Pushover Analysis Approach
Abstract: In urban India, reinforced concrete buildings with open ground stories designed for parking purposes are quite prevalent. These soft-story structures have faced severe damage and even total collapse during significant earthquakes in various regions, including the 1999 Taiwan earthquake, the 1999 Turkey earthquake, the 2003 Algeria earthquake, and the 2001 Bhuj earthquake, where approximately 1,500 medium-rise open ground-story buildings demonstrated extreme vulnerability. Given this vulnerability, the primary objective of this …

Analysis of Retrofitting Concrete Structure Using FRP Laminates
Abstract: Retrofitting is referred to as modifying existing equipment or structure with additional or new components or members. To make older structures more resistant to accidents or seismic activity, retrofitting is referred to as modifying existing equipment or structures with new or additional members or components. An existing structure is less susceptible to damage when it is retrofitted. The use of retrofitting is on the rise right now. The structures' strength, …

Leveraging IoT for Real-Time Disaster Management: Enhancing Preparedness and Response Through Smart Monitoring
Abstract: Natural disasters, including floods, earthquakes, and wildfires, pose risks to human life, infrastructure, and the environment. Many of the technological innovations are there, but in managing such disasters, there still is room for inefficiencies resulting from communication delay, unavailability of real-time data, and poor coordination at times. The inefficiencies lead to response times that are too long, inappropriate allocation of resources, and increased vulnerability to the impacts of disasters. Integration …

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 …
