Cubic B-splines for Isogeometric Analysis of Laminated Composite Plates Subjected to Hygroscopic Loading Using Classical Laminated Plate TheoryBy K NV Chandrasekhar, V. Bhikshma, Madhusudhana Chary, Maduri Venkat Sai
Abstract: Composite laminates are inevitably used in several engineering structures due to their high strength and stiffness to weight ratio. The laminates are subjected to change in moisture content and the flexural behavior leads to change in the strength. Presence of moisutre may induce residual stresses and strains. Isogeometric analysis is a well-proven method to perform analysis of laminated composite plates. The main focus of this study is to apply isogeometric …

Design of Openings and Static and Vibrational Analysis of RCC Cellular BeamBy P. Manisha, G. Harish, Ch. Gowtham Raj, K NV Chandrasekhar
Abstract: In concrete arena, RCC cellular beams have less weight compared to solid beams which in turn reduce the weight of columns and footings. All real physical structures, when subjected to loads or displacements, behave dynamically. In this study, we have performed the static analysis and vibration analysis of a three-dimensional reinforced cement concrete cellular beam. The nodal displacements have been found and the stresses are determined. The principal stresses are …

Multi-population Search Engines for Topology Optimization of Continuum StructuresBy K NV Chandrasekhar, Sangu Swapna
Abstract: This paper deals with the complex design domains, which usually require higher computational effort, and further tuning of parameters for algorithms is not practicable in terms of time and effort required. Multi search engines can be one such option wherein the search particles in groups are searching the design domain. Aqua search metaheuristic optimization algorithm is used to effectively explore and exploit the search domain. It is observed that this …

Optimal Green Design of a Reinforced Cement Concrete FootingBy K NV Chandrasekhar
Abstract: The goal of a civil engineer is not only to design, analyse, construct and maintain a safe green environment for the living but also to provide an efficient design which optimizes the use of concrete. The design of footing plays an important role in the design of structures carrying heavy loading. The footing is the vital element of the structure which carries the entire load of the structure and transfer …

Optimal Design of Gusset plate and Analysis of Bailey Steel Truss JointBy K NV Chandrasekhar, Akhileshwar Reddy, Arunodaya Reddy
Abstract: In order to achieve safe and economic steel structure joint, we are going to design a gusset plate such that its shape is optimized by achieving the same amount of strength. In conventional method of designing a joint we make sure that gusset plate is able to bear the load and joint is safe, but lot of material is wasted where there is no stress induced. So, to avoid this …
