Abstract:

The design of large panel shear walls must take into account the fact that the strength and stiffness characteristicsof the vertical joints between panels are different from those of the wall panels themselves. . .This paper summarizes current knowledge of the behaviour of vertical, keyed shear joints as observed on small test specimens and outlines the implications of this knowledge on the design of a complete wall system. The paper os based primarily on reference (17), which was prepared under the auspices of CIB Commission W23A, Loadbearing walls.

Abstract:

An article outlining some of the constraints that exist in the development of a viable industrialized concrete industry in the United States. Items considered are building codes, ACI Standard 318, design decisions and government and labor constraints. Suggestions and solutions to some of these problem areas are presented.

Abstract:

The paper reviews the development of the structural precast concrete industry in the U.K. over the last 15-20 years, specifically in terms of the activities of Concrete Limited, and generally as regards other companies, with particular regard to the development of an industrialized system of construction for various markets - apartments, car parks, offices, schools, etc., and flooring generally; it comments on current markets. It discusses the problems which have arisen as a result of Ronan Point and the subsquent activities including Building Regulations and existing Codes of Practice and the recently issued Unified Code based on Limit State Design. It briefly touches on differences between the U.K. and America.

Abstract:

This paper describes recent British tests concerned with catenary, or tensile membrane, actions, which may prevent local damage to a structure spreading to cause a progressive collapse. Reference is made to preliminry tests of structure, some of which indicated the considerable potentialities of such behaviour. More detailed tests studying the tensile strengths and ductilities of various components are described, as are experiments on floor strips with lost supports. Finally, possbile methods of predicting catenary resistance are discussed, although no general design guidance seems possible at this stage.

Abstract:

In order to identify and define abnormal forms of loading a classification system for all forms of structural loading on buildings is developed. Statistics relating to the incidence and consquence of the following forms of abnormal loading are then summarized: gas explosion, bomb explosion, vehicular collision. An attempt is then made to evaluate the structural signifance of each of these loadings with particular reference to multi-unit residental and mutli-story commerical, i.e., engineered, buildings.
