Properties of Structural-Steel Shapes

Transcription

1 E Proties of Strutural-Steel Shapes In the following tables, the proties of a few strutural-steel shapes are presented as an aid to the reader in solving problems in the text. These tables were ompiled from the extensive tables in the Manual of Steel Constrution, published by the Amerian Institute of Steel Constrution, In. (Ref. 5-).
