Dynamic Fail-Safe Behavior of Steel Structures: Theoretical and Experimental Studies of Some Steel Structures in the Area of Primary Damage

摘要

The fundamental behavior and the capacity of steel structures subjected to loss of interior load bearing elements are studied. The ultimate load bearing and deformation capacity of certain beam to column connections and the dynamic fail safe behavior of some ordinary steel structures are investigated in detail. A number of different geometrical models of steel structures in the area of primary damage are analysed. Both bending and catenary action of the models are treated and the strength properties of both members and connections are considered. Two types of connections are investigated, the bolted heel connection and the bolted end plate connection (with a degree of moment rigidity of 25%). No stability problems are treated. A rigid body method of analysis is applied.
