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.

SP27-04

Date:

Author(s):

Mark Fintel and Fazlur R. Khan

Publication:

Symposium Papers

Volume:

27

Abstract:

A procedure is presented to analyze frames of multistory structures for the structural effects of differential elastic and inelastic shortening between adjacent columns or walls..Results are presented of a 6 1/2 year observation of elastic plus creep and shrinkage strains of a number of columns and walls in the second story of a 38 story building. The measured strains are compared with the analytically computed and found to be in acceptable agreement.

Publication:

Symposium Papers

Volume:

27

Abstract:

This paper presents a review of methods for predicting creep, shrinkage and temperature effects in concrete structures as related to reinforced beams and one-way slabs, two-way construction, prestressed beams, and composite beams. The paper is generally consistent with the ACI Building Code (ACI 318-71) and includes material indicated in the Code, but not specifically defined therein.

Date: 

January 1, 1971

Author(s):

James N. De Serio

Publication:

Symposium Papers

Volume:

27

Abstract:

This paper outlines some of the many problems and structural distress conditions which can be caused by insufficient provision in the design and construction if thermal changes are neglected. Four structures, completely different from each other are discussed.

Document: 

SP27-01

Date: 

January 1, 1971

Author(s):

ACI Committee 209

Publication:

Symposium Papers

Volume:

27

Abstract:

This paper discusses the current state of knowledge in the area of time-dependent deformation of plain concrete. The paper is divided into three broad areas: effects of concrete constituents, effects of environment, and effects of stress.
