Document: 

SP9-05

Date: 

January 1, 1964

Author(s):

Boris Bresler and Lawrence Selna

Publication:

Symposium Papers

Volume:

9

Abstract:

The influence of environment on time-dependent behavior of reinforced concrete structures is introduced and the principal variables discusssed. Deformation due to variable stress history is described in general terms. A simplification in determining specific creep function is explored. Methods for analysis of stresses and deformation which account for time- and environment- dependent processes are outlined.

Volume:

Abstract:

Develops a procedure for including the effects of creep and shrinkage in design and analysis. The objective of the procedure is to permit the designer to automatically satisfy deflection criteria as well as allowable working stresses. Working equations for the general case are developed and equations are given for special cases, including beams with and without compressive reinforcement, and prestressed concrete beams.

Ori lshai

Publication:

Symposium Papers

Volume:

9

Abstract:

The influence of amount of torque, duration of loading, age on loading, humidity conditions, and sand content on various deformation components was studied. A theory, formulated on the reversible and nonreversible time-processes taking place in the mortar, is presented that attributes shrinkage, swelling, and creep and its recovery to water migration within the cement gel.

Date: 

January 1, 1964

Author(s):

lqbal Ali and Clyde E. Kesler

Publication:

Symposium Papers

Volume:

9

Abstract:

A hypothesis for creep is presented in terms of the microstructure and properties of hydrated cement. An experimental investigation, designed to provide a quantitative basis for the hypothesis, is briefly described. Procedures are presented for estimating creep in terms of the volumetric composition of the concrete, the degree of hydration, and the observed free shrinkage characteristics.
