SP27

Date: 

January 1, 1971

Author(s):

Editor: Raymond C. Reese

Publication:

Symposium Papers

Volume:

27

Abstract:

SP27 Much has been written on the damaging failures resultingfrom designs without adequate provision for the effects of creep, shrinkage and temperature, The object of this symposium volume is to combine the laboratory and actual field experience into a working procedure for estimating the effects of volumetric changes. By comparing the experiences of researches and design engineers this publication aims for an eventual mathematical procedure that could be as well agreed upon as movement distribution.

SP27-13

Date: 

January 1, 1971

Author(s):

D.E. Branson and M.L. Christiason

Publication:

Symposium Papers

Volume:

27

Abstract:

Presented are design procedures for predicting strength and elastic properties, creep, and shrinkage as a function of time. Continuous functions are provided for all standard equations and correction factors, so that the procedures readily lend themselves to computer solution.

Author(s):

Publication:

Symposium Papers

Volume:

27

Abstract:

Creep, shrinkage and delayed thermal dilatation of concrete at low stress are caused by mass transport of water and other molecules along thin layers in the microstructures. The theory of the consitutive equation based on this mechanism is summarized and, as an example, a plausible explanation of the phenomenon of drying creep is presented.

SP27-19

Date: 

January 1, 1971

Author(s):

C.H. Wang

Publication:

Symposium Papers

Volume:

27

Abstract:

Data on creep of concrete subjected to various loadings at elevated temperatures rang 200F (93.3C) to 800f (426.8C) are presented, together with the informations of specimens failure in test. Compressive strength and thermal expansion coefficient of concrete in this temperature range are also provided. Relationships between creep, stress strength ration and time under loading are shown in curves.

SP27-16

Date: 

January 1, 1971

Author(s):

Lev Zetlin, Charles H. Thornton, I. Paul Lew

Publication:

Symposium Papers

Volume:

27

Abstract:

A simplified approach for the analysis of self induced stresses due to internal straining of concrete is presented. The approach has been broken in three steps.
