Download or read book Time Effects in Concrete Structures written by R. I. Gilbert and published by Elsevier Publishing Company. This book was released on 1988 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inability of designers of concrete structures to recognize and quantify the non-linear effects of cracking, creep and shrinkage is a common cause of serviceability failure. Such failures include excessive deflection, camber and/or shortening of members and excessive cracking which may cause aesthetic or durability problems. This book provides practising engineers with practical and usable techniques for predicting the non-linear effects of creep and shrinkage on the in-service behaviour of concrete structures. Both cracked and uncracked reinforced, prestressed, and composite members subjected to sustained loads or sustained deformations are considered. Analytical procedures are developed for the calculation of instantaneous and time-dependent stresses and deformations on cross-sections in both simple and continuous members. Numerous self-contained worked examples which clearly illustrate the analytical procedures are included. A wide variety of practical situations is considered. Listings of microcomputer programs for a number of the analyses are also presented.
