Abstract:
Discusses the philosophy for planning and design of buildings with exposed columns, based on performance and cost considerations. Two planning approaches are discussed: Designing for movement limitation and accommodation of the computed movement with appropriate details of partitions and frame. Application of the two philosophies is explained by showing examples of recent prominent structures. The result of a survey of 15 buildings with exposed columns ranging from 16 to 46 stories is presented. The observed behavior of partitions and frames is described. Temperature movement measurements of nine structures is also presented, and the measured movements compared with analytically predicted movement.
