A structure as shown in Figure 4 is supported by pinned-end support at both columns. The mass of the structure lumped at the slab level can be idealized as 190 kg/m. If a new column is proposed to be added in the middle of the slab, figure out a suitable support for the new column, so that it is strong enough to restrain an earthquake. Explain and illustrate the simplified model of your answer. Take I= 3.53 x 108 mm² ; E = 200 GPa ; g = 9.81 m/s².
