Paper Title :
Seismic Evaluation Of Multistorey RC Building With Openings In Unreinforced Masonry Infill Walls With User Defined Hinges

Author :Praveen Rathod, S.S.Dyavanal

Article Citation :Praveen Rathod ,S.S.Dyavanal , (2014 ) " Seismic Evaluation Of Multistorey RC Building With Openings In Unreinforced Masonry Infill Walls With User Defined Hinges " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 71-76, Volume-2,Issue-10

Abstract : In buildings it is very common to use unreinforced masonry infilled frame structures. These types of structures are used for multistoried construction in the developing countries. Window and door openings are inevitable part of the infill walls. Opening in infill walls significantly reduce the lateral strength and stiffness of RC frames. An attempt has been made during the present study the behavior of performance based seismic vulnerability of two-dimensional RC multistory building models, with the varying percentage of central openings in unreinforced masonry infill walls ranging from 10 to 35%. Building is considered as official building which is located in zone III. The unreinforced masonry infill walls are modeled as pin-jointed single equivalent diagonal struts. The study is carried out on G+3 and G+6 storey buildings were considered to represent medium and high rise buildings. Equivalent and response spectrum analysis was performed on infill as a brick and solid concrete block with various percentages of central openings using SAP 2000 V14.2 software. Nonlinear static pushover analysis was carried out using user defined hinge properties as per the FEMA 440. The results are compared with the parameters natural period, base shear, lateral displacement & hinge status at performance point amongst the models.
