Calculation Example: Shear force On A Column

A force is acting at the top of a building frame as shown. The supporting columns are of equal height and are fixed at the base. The modulus of elasticity E is the same for each column. Assuming the top plate is rigid and


What is the shear distributed to the first column?

Calculation Example: Axial Force On A Column

For the building shown below, the forces on the wall are as illustrated. What is the axial force on the column due to the lateral loads?

Each of the following columns supports a block of identical mass, m. The columns are fixed at the bottom and free at the top. The height of the first column is twice the height of the second column. The modulus of elasticity, E, and moment of inertia, I, for both columns are the same. The systems have natural periods of vibration of T1 and T2, respectively. Neglecting the weight of the columns, what is the natural period of vibration for the first system?
