SP24-04

Date:

Publication:

Symposium Papers

Volume:

Abstract:

The highly important question of accuracy of model results is explored in this paper. Before a decision is made to proceed with a model study the decision maker should be cognizant of the accuracy which can reasonably be expected in a model study, and once the decision to proceed is made, the model enigneer should know of the techniques and procedures which will lead to useful dependable results.

Author(s):

James E. Carpenter, Frederic Roll and Maier I. Zelman

Publication:

Symposium Papers

Volume:

24

Abstract:

Techniques and materials for the construction and testing of models of concrete structures are discussed in this paper. Both elastic and ultimate strength models are considered. Elastic models are treat briefly. Time effects in commonly used plastic materials and complications in instrumentation are discussed. Materials to simulate both the steel and the concrete in ultimate strength models are discussed and references to detailed investigations are given. Fabrication, instrumenation and testing methods are described.

Publication:

Symposium Papers

Volume:

Abstract:

This paper presents the principles of model analysis with particular reference to concrete structures. Emphasis is placed on the use of direct models for the study of both the elastic and the inelastic behaviors up to and including the ultimate strength.

Publication:

Symposium Papers

Volume:

Abstract:

Scale models are becoming increasingly more important in research on structural concrete and are also being used quite widely in the design problem. Presenting a justification for the use of models in these areas the authors discuss the advantages and disadvantages of structural models in general.

Symposium Papers

Volume:

24

Abstract:

In the last 20 years, model tests for the study of static structural problems have been extensively used at the Laboratorio Nacional de Engenharia Civil. Some of these models have been used to solve design problems of reinforced concrete structures difficult to approach by analytical methods. . .Some results of the model tests are compared with the observed behavior of the prototype in this summation of the author's experience.
