Considerations on the current story shear coefficient distributions using base-isolated steel warehouses with an inhomogeneous mass and stiffness

With the development of internet marketing, logistics bases have been increasing recently. Under the influence of the 2011 Tohoku Earthquake, base-isolated steel warehouses are on the increase. As the roofs of most warehouses are made of steel plates and with small loads, the rooftops of most warehouses are light. However, the current story shear coefficient distributions of base-isolated buildings are based on the buildings with a homogeneous mass and stiffness. So, this report shows a verification on the story shear coefficient distributions of base-isolated steel warehouses with an inhomogeneous mass and stiffness.
