1. Shear walls are a necessary element in the seismic design of buildings. Shear walls provide large strength and stiffness , which significantly reduces lateral sway of the building and thereby reduces damage to the structure. The best position for the shear walls is in the centre of each half of the building. (img B)…

1.        a) SYMMETRY : The given diagram is symmetric in nature. A symmetrical, well-distributed in-plan layout of structural elements is appropriate to achieve uniformity. Symmetry should be sought both in what concerns the plan wise distribution of stiffness and strength, but also that of mass distribution,…

Step 1 : Calculation of Mn Hence, Mn1 = 3.86m Mn2 = 3.86m Mn3 = 3.86m Mn4 = 3.86m Mn5 = 3.86m   Step 2 : Calculation of Ln  Hence, Ln1 = 4.121m Ln2 = -1.29m Ln3 = 0.68m Ln4 = 0.381m Ln5 = 0.175m   Step 3 : Calculation of Mn* Hence, Mn*1 = 4.398m Mn*2 = 0.432m Mn*3 = 0.119m Mn*4 = 0.357m Mn*5 = 0.0079m   Step 4 : Calculation…

 1. Given that the degree of freedom is 3. The elements ki1 in the first column, we determine the stiffness matrix by imposing u1=1 , with u2=u3=0. The elements ki2 in the second column, we determine the stiffness matrix by imposing u2=1, with u1=u3=0. The elements in ki3 in the third column, we determine the stiffness…

1 (a) MODE OF FAILURE : The above crack is due to the Shear failure of the beam. Shear failure occurs when the beam has shear resistance lower than flexural strength and the shear force exceeds the shear capacity of the materials of the beam. Cracks in concrete beams due to increase in their shear stress appears near the…
