The influence of column stiffness, damping and foundation interaction on the earthquake response of multi-storey shear buildings is analysed. Using Ramberg-Osgood and bilinear formulations, the moment-curvature and shear-deflexion relationships for the columns are computed, based on the general nonlinear inelastic stress-strain relationships which include the hysteretic loops and strain hardening range. It is found that damping can sometimes prevent buildings from going into inelastic deformation. The decrease in column stiffness causes a decrease in the natural frequency of the building but increases the amplitudes of the forced vibrations. Avinash Singhal

Dr. D. Robak: As one closely connected with the design of the hangar, from the initial discussion with the user to the day of its final completion, I would like to enlarge on the reasons why the scheme described by Mr. Taylor was finally adopted.

Discussion Tower Block Development, Guy's Hospital, London by G. Mould

Discussion Tower Block Development, Guy's Hospital, London by G. Mould

Mr. G. Mould: When completed, the tower block at Guy’s Hospital will be an extraordinary building, not because it incorporates any sensational new structural concepts nor because it is a particularly bizarre piece of architecture. This is the first time that a 32 storey hospital has been produced in this country, and there are few abroad either. I have not tried to present a highly technical description of the structural design of a highrise building, but I have emphasized the structural engineer’s contribution, as part of a team, to meeting the accommodation requirements of a very wide crosssection of the medical profession, and at the same time meeting the physical requirements of the planning authorities.
