Abstract:Reinforced concrete buildings must be proportioned to satisfy three limit states, serviceability, ultimate strength, and stability under sustained loads. This paper includes a detailed discussion of the recommended procedures and assumptions to be used in the design of reinforced concrete buildings for wind loads at these various limit states. Definition of the appropriate lateral load intensity, consideration of the structural parameters to be considered in the analysis, and discussion of suitable acceptance criteria is included. Differences in member properties at the limit states are prescribed based on variations in the degree of member cracking that can be expected at the load levels under consideration. The accurate prediction of the lateral stiffness of flat slab frames is also discussed. A summarization of the proper procedure and parameters to be used in the analysis of second order effects (P-?) is provided. Various other parameters affecting the analyses of buildings under sustained loads are addressed, including beam-column joint stiffness, foundation fixity, etc.
