SP22-01

Date: 

January 1, 1969

Author(s):

Edward Cohen

Publication:

Symposium Papers

Volume:

22

Abstract:

Reliability, econonmy, and simplicity should be the criteria for selecting an achorage or connection detail. Each anchorage must be of adequate strength to perform its assigned task, must be the proper type for the application, and must be able to provide satisifactory service throughtout the life of the structure. . . Examples are presented to point up the difficulties, accomplishments and goals for proper anchoring of and to concrete.

Abstract:

In selecting the best anchoring device for the steel rails of the Montreal subway system a number of critical factors were considered, including resistance to the pulling force, resistance to displacement, early strength, stability, ease of installation, cost and adaptability to the project.

Publication:

Symposium Papers

Volume:

Abstract:

Advantages of explosive driven fastenings in concrete, their application, energy sources, design prinicples and mechanics of the connections are presented. Influencing factors such as aggregate and compressive strength are discussed and supported by test data reduced to simple graphs. Tables describe recommended safe working loads in shear, tension and reistance to vibration. . .The conclusions support the economy and portability of such systems.

Symposium Papers

Volume:

Abstract:

Performance characteristics of powder driven fastners installed in hardened concrete ranging in age from 30 ywars to 30 days indicate that failure in both shear and tension is apparently the direct results of frequent misapplication.

Date: 

January 1, 1969

Author(s):

Ben L. Bird

Publication:

Symposium Papers

Volume:

22

Abstract:

There are six general considerations for fasteners: (1) load level, weight held; (2) load condition-dead, variable, vibratory, shock; (3) base material; (4) atmospheric condition; (5) in-place cost and (6) simplicity of design.
