Abstract
A ten-storied building with length variations of shear walls, which are perpendicular to the lateral load acting on the building, has been studied here. The finite element based software, ETABS (version 9.6) has been used for determining the moment at different area objects due to the lateral load and Simpson’s one-third rule has been used to calculate the line moment from mesh area. Five different shear wall lengths- 4.5ft, 5.5ft, 6.67ft, 7.5ft and 8.5ft, are included here. The study shows that, moment in magnitude has been increased with the increasing of shear wall length but the percentage of total moment passed through the column strip is decreased and vice versa for middle strip. The moment in magnitude at column strip decrease by increasing of shear wall length but the optimum length will be 33% (approximate) of total span. The moment percentage of column strip moment passing through effective (c+3h) strip decreases by increasing of shear wall length.
Highlights
Flat Plate concrete slabs are not preferred in high rise buildings hotels, motels, hospitals and residential buildings etc-- for vulnerability under lateral loads such as wind and earthquake as flat plate transforms lateral loads to columns without the help of beams, column capitals and drop walls
It is shown that, the properties of moment remained same with the length variation of shear walls such as moment for line A to GL is negative and GR to M is positive for all shear walls
By increasing the length of shear walls, the percentage of total moment passed through the column strip will decrease and increase in middle strip
Summary
Flat Plate concrete slabs are not preferred in high rise buildings hotels, motels, hospitals and residential buildings etc-- for vulnerability under lateral loads such as wind and earthquake as flat plate transforms lateral loads to columns without the help of beams, column capitals and drop walls. An earthquake load is calculated by seismic coefficient method using IS 1893 (PART–I):2002 These analyses were performed using STAAD Pro. The study has been carried out to determine the strength of RC shear wall of a multistoried building by changing shear wall location. H. Rahangdale et al analyzed G+5 Storey building in Zone IV with some preliminary investigation by changing various position of shear wall with different shapes to determine parameter like axial load and moments.
