Abstract:
The design of modern architectural structures increasingly requires thin slabs that minimize the need for extensive support systems, with post-tensioned slabs featuring unbounded tendons being an ideal solution. These slabs, commonly used in bridge and storage tank construction, are now being applied in buildings due to their ability to handle long spans efficiently. The most prevalent system for two-way slab construction utilizes mono-strand unbonded tendons, which enable the concrete to be kept predominantly in compression, enhancing its structural efficiency. Post-tensioned slabs offer the thinnest slab designs, reducing material usage and providing the ability to counteract deflections due to prestress. This technology uses high-strength steel tendons to compress the slab, offering significant advantages over traditional reinforced concrete. The project focuses on developing a design code for post-tensioned two-way slabs with discontinuous edges, using a MATLAB-based methodology. The automated design process accounts for factors such as the number of tendons required in both directions, limit state of collapse, deflection under service loads, and bending stresses, all in accordance with IS Design Code standards. This approach not only simplifies the design process but also ensures the structural integrity and efficiency of the post-tensioned slab system.
Aim:
The aim of this project is to develop an automated design methodology for post-tensioned two-way slabs with discontinuous edges using MATLAB, in accordance with the IS Design Code. The objective is to determine the number of tendons required in both directions for optimal design, while simultaneously ensuring that the slab meets the limit state of collapse, deflection due to service loads, and bending stress criteria.
Objective:
The objective of this project is to develop a MATLAB-based design code for post-tensioned two-way slabs with discontinuous edges. The design will focus on determining the number of tendons required in both directions based on given input parameters. The project will also ensure that the slab design satisfies the limit state of collapse, deflection due to service loads, and bending stress as per the IS Design Code. Additionally, the automated design process will optimize the design procedure to ensure efficient and accurate structural performance while minimizing material usage.
