“…They proposed a new type of buckling restrained braces and conducted tests and finite element analysis on them. From the study done by (Khanal, 2020;Khanal et al, 2023), a numerical analogy can be performed on implementing nonlinear one-dimensional and three-dimensional buckling equations in the material behavior using the software MATLAB and ANSYS APDL. This analogy technique helps to validate the real buckling behavior using a numerical approach [23][24].…”

In this study, we investigate the behavior of a buckling restrained brace frame made of a shape memory alloy when subjected to explosive loads. To accomplish this, we initially loaded a conventional braced frame with a span of 6 meters and a height of 3 meters with explosive forces. The simulation and validation processes will be conducted using the ABAQUS software. After validating the results, we examine eight additional models using ABAQUS software. These models are divided into four groups. In each group, the first sample is constructed from plain steel alloy, while the second sample is made from a shape memory alloy with identical specifications to the first sample. In the first group, the explosive load is set at 10 kilograms, in the second group, it is 30 kilograms, in the third group, it is 50 kilograms, and in the final group, the mass of the explosive material is 100 kilograms. The analysis results reveal that as the amount of explosive material increases, displacement and stress in the samples rise. The displacement increases significantly in the last set of samples (with 100 kilograms of explosive material). By incorporating shape memory alloy into the samples, especially with lower quantities of explosive material, it is possible to partially restore the structure to its initial state, thereby reducing the severity of damage inflicted upon it. Even with higher amounts of explosive material, a substantial level of restoration can be achieved, further minimizing structural damage.

“…A building's heating, ventilation, and air conditioning system (HVAC) creates a climate that allows for maximum comfort by compensating for changing climatic conditions [4], [5]. The humidity level inside the building must be maintained below a critical level for the survivability of electronics devices because excessive humidity leads to many deleterious effects on moisture sensitive electronics devices [6], [7]. Efficiency improvements in HVAC systems can lead to substantial savings.…”

This paper introduces an innovative approach to create cost-effective supply air and return air ducting systems, aiming to optimize indoor conditions in commercial buildings. Following ISHRAE standards and employing CAD Plans, theoretical heat loads are compared with practical E20 Sheet results, ensuring comprehensive accuracy. These calculations drive cubic feet per minute (CFM) determinations, guiding ducting design and equipment selection. Our distinctive contribution lies in seamlessly integrating theoretical and practical data, fortifying system robustness. Furthermore, our commitment to sustainability bolsters energy efficiency. The study concludes by aligning the estimated 80.51 TR equipment capacity with the 70-80 TR range, affirming precision and cost-effectiveness. This work furnishes a pragmatic framework and underscores its relevance in contemporary energy-conscious installations.
