An Optimal Seismic Force Pattern for Uniform Drift Distribution

New Lateral Force Distribution for Seismic Design of Structures Based on Seismic Demand Ratio

The design of earthquake-resistant buildings starts with defining the maximum lateral earthquake forces or their resultant. The amount of these forces depends on various factors, including coefficient of system behavior which depends on overstrength and its ductility. In this study, a method is presented for designing an earthquake-resistant system in which the distribution of lateral forces is...

A Seismic Design Lateral Force Distribution Based on Inelastic Response

It is well recognized that structures designed by current codes undergo large inelastic deformations during major earthquakes. However, lateral force distributions given in the seismic design codes are typically based on results of elastic response studies. In this paper, current code lateral force distributions are reviewed in view of the results obtained from nonlinear dynamic analyses of sev...

Optimal Trajectories and Force Distribution for Cooperating Arms

The optimization of trajectories and actuator torques for a dual arm manipulation system is considered. Given the starting and nal conngurations, we nd the trajectories that minimize (a) the integral of the norm of the vector of derivatives of the actuator forces; and (b) the integral of the norm of the actuator forces. In this way both kinematic and actuator redundancy are resolved. The optimi...

Sub-optimal algorithms for force distribution in multifingered grippers

The work described in this paper addresses the problem of determination of the appropriate distribution of forces between the fingers of a multifingered gripper grasping an object. The system is statically indeterminate and an optimal solution for this problem is desired for force control. A fast and efficient sub-optimal method for computing the grasping forces is presented. This method is bas...
