ANALYSIS OF MULTISTOREY BUILDING BY USING SOFTWARE
In today’s fast-paced construction industry, efficiency in analysis and design has become essential for structural engineers. To improve both accuracy and time management, modern software tools such as STAAD-Pro and ETABS are widely used for the analysis of multi-storey buildings. The structural analysis of such buildings requires careful consideration of various loads, including dead load, live load, and other possible external forces, to ensure safety under different conditions. Traditional analysis techniques like the moment distribution method, cantilever method, and portal method provide fundamental understanding, while the matrix method forms the basis of most software-based analysis. This project aims to study the behaviour of a multi-storey building by performing analysis through both manual calculations and software tools, allowing a comparison between conventional and modern approaches. The dead load &live loads are applied and the analysis for beams, columns. STAAD Pro, and ETABS. We conclude that software is a very powerful tools which can save much time and is very accurate in analysis. Thus, it is concluded that software is more suitable for the analysis of a multistoried building.
A REVIEW OF CRACKING BEHAVIOUR IN UNDERGROUND REINFORCED CONCRETE BOX STRUCTURES CONSIDERING SOIL–STRUCTURE INTERACTION EFFECTS
Underground reinforced concrete box structures are the backbone for any infrastructure projects, and these are widely used as a tunnels, road and railway underpasses, utility corridors, car parks and metro infrastructures because of their higher strength, durability, and comparatively easy construction. One of the main issues affecting their long-term performance is cracking, which can impact its durability, serviceability and water tightness. This review paper examines previous studies on the cracking behaviour of underground RC box structures, with a focus on the effect of soil stiffness and soil structure interaction (SSI). The review discusses how soil conditions influence stress distribution, deformation, bending moments, axial forces, shear forces and crack formation in these structures. Existing research on crack initiation, crack growth, soil–structure interaction, and finite element modelling is also reviewed. The study compares various design methodologies used to determine and control cracking and highlights the limitations of current research. It was found that although many studies have investigated soil–structure interaction and structural behaviour, only a limited researcher have focused on how changes in soil stiffness affect the cracking. Based on the reviewed literature, several research gaps have been identified, and the findings of this review can help researchers, engineers and practitioners to better understand the factors affecting cracking and support the development of safer and more durable underground reinforced concrete box structures.
Seismic Vulnerability Assessment, Non-Linear Pushover Analysis, and Performance-Based Design Optimization of Multi-Story Reinforced Concrete Framed Structures with Structural Shear Walls
Rapid urbanization and vertical densification in seismically active zones necessitate the structural design of robust framing systems capable of resisting severe lateral earthquake forces without catastrophic collapse. Conventional reinforced concrete (RC) moment-resisting frames frequently suffer from excessive lateral drift, P-delta effects, and torsional irregularities when subjected to high-magnitude seismic ground motions. This research evaluates the seismic vulnerability, plastic hinge formation hierarchy, and performance-based design optimization of multi-story RC framed structures integrated with strategically positioned structural shear walls. Utilizing advanced finite element software, non-linear static pushover analyses and dynamic time-history simulations were conducted on 12-story building models designed in compliance with Indian Standard IS 1893 (Part 1): 2016. The analytical results demonstrate that incorporating reinforced concrete shear walls effectively controls maximum inter-story drift ratios, reduces bending moment and shear demands on peripheral columns, and redirects seismic energy dissipation uniformly across structural members. Performance-based plastic hinge state distributions confirm superior structural resilience and ductility capacity under maximum considered earthquake (MCE) events.
Digital Site Progress Monitoring and Crack Detection Using UAV Photogrammetry: A Critical Review
The demand for objective, rapid, and automated construction-site inspection has generated significant interest in the application of unmanned aerial vehicles (UAVs) for construction management and structural assessment. UAV photogrammetry facilitates the capture of high-resolution images and three-dimensional reconstruction at construction sites and civil infrastructure, allowing for a more economical alternative to frequently repeated manual surveys, and for certain applications also terrestrial laser scanning. This review highlights UAV photogrammetry as the critical technology that ties together digital construction progress monitoring and crack detection. The paper reviews recent advances in Structure-from-Motion photogrammetry, point-cloud generation and workflows for Building Information Modeling (BIM) integration, deep learning and digital twin construction. Point clouds derived from UAV can be utilized for comparison of As-built vs. as-planned, quantities estimation, component recognition and progress verification while high-resolution UAV imagery offers automated crack detection, segmentation, measurement and spatial localization. Yet the accuracy of photogrammetry still depends on image overlap, ground sampling distance, camera calibration, surface texture, illumination, occlusion flight geometry and georeferencing quality. In the case of crack measurement, problems compound further since very small defects can become close to the spatial resolution limit of the images captured. The review concludes with the recommendation to utilize UAV photogrammetry for efficient integrated progress and condition monitoring, but warns against treating it as an infallible substitute for conventional surveying or engineering inspection. Reliable digital site-monitoring are likely to be future systems based on UAV photogrammetry, BIM/digital twins-belued by AI-based defect analysis and uncertainty estimation requiring adaptive flight planning.
