This paper describes the step-by-step design procedure of a simplified approach proposed for use in practical design of base isolated multi-storey structures. The proposed method can be used to accurately estimate the inertia forces, not only at the level of the isolation devices but throughout the height of the structure.

Structural Mass

Hybrid structure has shown some great features in the earthquake-resistant design. However, due to the different properties between the combined building systems, the distributions of structural mass and stiffness are prevalently irregular in breadth or height, which makes the widely used equivalent lateral force (ELF) method powerless to predict the seismic shear force of such hybrid structure. This study proposed a simple design procedure for determining the concerned seismic shear force of low-rise wooden horizontal hybrid structure in the preliminary linear design. The dual equivalent lateral force (DELF) method is presented that permits the extension of the ELF method by separating the hybrid structure into two independent substructures. It is shown that the proposed DELF method is sufficient to provide a reasonable estimation of the seismic shear force with satisfied accuracy.

Tolerable Level

A procedure for earthquake-resistant design is developed to limit the potential damage of buildings to a tolerable level. The procedure is based on the damage model developed earlier (Park and Ang, 1984) in which structural damage is expressed as a function of the maximum deformation and dissipated hysteretic energy. The tolerable degree of damage is defined on the basis of calibration with observed damages from past major earthquakes. The design method is examined in the context of reliability.

Design Requirements

In this paper a simple and efficient procedure for optimum dimensional synthesis of gripping mechanisms is presented. The proposed design method is based on a suitable formulation of grasping performance of gripping mechanisms and makes use of a description of mechanisms by means of natural (fully Cartesian) coordinates. The optimization design problem is formulated by an objective function describing the main grasping performance and constraints prescribing practical design requirements and mechanism peculiarities. A numerical example is reported and discussed to illustrate the engineering feasibility of the proposed design procedure.
