| Abstract: | This paper deals with the dynamic behaviour of pin-jointed, steel-framed buildings which derive stiffness from bracing and cladding, and their response to earthquake loading. The first part of the paper considers the best way to obtain an analytical model, using the natural frequencies and mode-shapes measured on a CLASP building in Nottingham employing eccentric-mass vibrators. The second part is a study of a key section of a CLASP hospital now under construction in Algeria, in which the earthquake-induced forces in the bracing are calculated. The final part is concerned with studies on two-storey and three-storey CLASP-type models, using different bracing arrangements. |
