Abstract - Multistory buildings are subjected to various
that can potentially impact temperature fluctuations within buildings. This refers to the temperature difference between the construction phase and the highest or lowest temperature of the summer or winter [2, 3]. The second element that is accessible is temperature control [1, 3]. The third component refers to the geometric system, proportions, and type of foundation connection of the buildings [1, 3]. The ultimate factor to be taken into account during the construction of the structure is the choice of construction materials [1, 3]. Multiple factors contribute to the fluctuations in temperature change and temperature gradient observed among different countries. Consequently, the use of different codes leads to variations in temperature gradients across different countries [4-7].
environmental factors, among which thermal loads play a significant role. Changes in temperature can induce stress, strain, and deformation in structural elements, potentially compromising the integrity and safety of the building. Despite the growing construction of high-rise buildings in urban areas, there is limited understanding of how varying and uniform thermal loads affect different building heights. This research aims to address the structural response of multistory buildings subjected to thermal loads by using Staad Pro simulation software. Specifically, it focuses on the thermal analysis of G+10, G+15, and G+20 buildings under different temperature load conditions, examining the impact of both varying and uniform thermal loads on the structural behavior. Moreover, it seeks to analyze the influence of uniform temperature forces on buildings of varying heights in compliance with Indian codal provisions. Identifying the critical thermal responses in these buildings will help in designing safer and more resilient structures. The objectives of current research are to evaluate the structural response of multistory building subjected to thermal loads using Staad Pro simulation software. The thermal analysis of G+10 building is conducted with varying temperature loads. The thermal analysis of G+15 building is conducted with uniform temperature loads. The thermal analysis of G+20 building with uniform temperature loads. The story drifts at G+10, G+15, and G+20 levels are significantly within the permissible limits set by IS 1893:2016.
2. LITERATURE REVIEW Prakarsh et. al. [8] In certain countries, steel buildings are not frequently employed. Steel-concrete composite constructions are required in major urban centers such as Delhi, Mumbai, and Bangalore due to the absence of horizontal expansion. Composite construction is extensively employed, and the steel industry is experiencing accelerated growth in nearly every country on the planet. The three primary factors of uttermost importance from a structural perspective are financial resources, construction duration, and structural integrity. In comparison to RCC structures, steel frameworks with infill demonstrate an 8% increase in maximum storey displacement.
Key Words: Thermal analysis, story drift, multi-story
1.INTRODUCTION
Sattainathan et. al. [9] In contrast to RCC constructions, the steel-concrete composite technology has gained popularity in this investigation. Several engineers find the complexity of analysis and design to be a challenge. Steel-concrete composite construction is the preferred method due to its numerous benefits over traditional building methods. Steelconcrete systems offer cost-effective structural solutions that are highly durable, efficient to construct, and exhibit exceptional seismic performance, as indicated by the findings. The utilization of steel-to-concrete ratios is advantageous for composite structures.
Reinforced concrete structures possess inherent vulnerability to thermal loads caused by factors such as fire, heat of hydration, service function, and other unavoidable conditions. The design of the structure must consider these loadings, as they may sometimes act as the main loading condition [1]. The prolonged duration of the construction process leads to the exposure of different structural components to varying temperatures. The thermal variations that cause displacements and stresses in a structure are separate from the temperatures experienced during installation and construction, which are outside the control of the designer. The design temperature change is a variable
