Comparative Study on Dynamic Behaviour of Various Grid Patterns on Concrete Floors
Rajalakshmi U | Linda Ann Mathew [7]
Abstract: An assembly of intersecting beams placed at regular interval and interconnected to a slab of nominal thickness is known as Grid floor or Waffle floor. These slabs are used to cover a large column free area and therefore are good choice for public assembly halls. The structure is monolithic in nature and has more stiffness. It gives pleasing appearance. In the present study, an attempt is made to compare the bending moment, shear force and displacement obtained from the dynamic analysis using STAAD Pro software for various grid patterns. The size of grid patterns are 9mx9m and five basic grid patterns are selected which are varied by increasing the intermediate beams. It is important to note that the grids are analysed for G+3 building. IS 18932002 is referred to apply dynamic loading on the grids and Response spectrum method is followed to apply the dynamic loading on the grids. The main aim of the study is to compare the above mentioned results obtained from the dynamic analysis of various grid patterns and study the behaviour of various grids under dynamic loading.
