Fiber-reinforced plastics are only just being discovered by civil engineers. Long used in expensive military and aerospace applications, they are beginning to find their way into structures....

Bibliography of Steel Columns
This book, which was prepared by the Committee on Compression Members of the Structural Division of the American Society of Civil Engineers, attempts to provide a complete bibliography...

Reliability of Elasto-Plastic Structural Systems
This paper proposes a method for generating safety margins and failure mode equations for elasto-plastic structures where interaction of load effects is taken into account. Structural...

Random Instability of Elastic-Plastic Frames
A concept of joint probability of elastic and plastic instability modes was formerly given for single columns and now it is extended for framed systems. A critical load is defined for...
