A Comparative Study of Displacement and Time Period in Mud Mortar Masonry Building with Changes in Modulus of Elasticity (Young Modulus) of Brick with Time

Sanjay Kumar Kawan


Abstract: Masonry buildings are generally built by brick, mud mortar with timber as joist. The structural health of these masonry buildings deteriorates with time. The quality of materials used in the building in this case brick elements deteriorate with continuous use and application of load and action of heat and cold temperature. Thus, due to continuous exposure to hot and cold weather, vibration force either due to earthquake force or vibration due to vehicular movements the materials deteriorate years by years. But it would take years and years of practical and theoretical calculation to observe and predict the exact percentage of deterioration thus, in the present study, it is studied for the deterioration which causes decrease in young's modulus of elasticity by 10 to 40 percent. It is observed from the analysis that the maximum effect to the structure will be created due to the decrease in elasticity causing high displacement of structures and increment in stress. As modulus of elasticity is directly associated with the stiffness of the structures, stiffness decreases with decrease in modulus of elasticity which will further cause increment of fundamental time period.
