The elastic and plastic behavior of ASTM A-36 tubular beam columns is studied. Experimental results for three tests of tubular beam columns are presented. These tests show that the tubular...

Discrete Dynamic Models for Elasto-Inelastic Beams
Three discrete physical models, obtained by lumping the flexibility and the mass of the continuous system, or both, are used to compute the dynamic response of beams. The beams may have...

Behavior of Hybrid Beams Subjected to Static Loads
Elastic and simple plastic theory are used to define the behavior of hybrid steel beams (beams with higher-strength steel flanges connected by lower-strength steel webs). Theoretical equations...

Shakedown Analysis of Some Typical One-Story Bents
Few analyses of frames subjected to variable repeated loading have been reported in the literature. This has been at least partly due to the fact that such analyses are laborious, partly...
