One storey building with 3m height is supported by three columns where two columns have pinned-end support and one column has fixed-end support. The distance between two columns is 4m. The mass of the structure can be idealized as 190 kg/m lumped at the roof level. All columns have I = 3.53 x 10^8 mm^4 and E + 200GPa. Determine the vibration frequency of the building. (Take g = 9.81 m/s^2). If a new building is to be constructed with...

Example 2 Suppose one truck is parked on a bridge as shown in the Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per feet, which is uniformly distributed. We can assume the bridge is rigid. We want to know what will be the reaction forces at the supports of bridge at the two ends 1000 lbe 200 Ib/ft 25 Force? 50 Force? Figure 1
