Focuses on the use of post-tensioning steel frame for building to handle earthquake loads in San Diego, California. Minimization of the need for field welding; Reduction of construction time; Concern about the structural fatigue of the post-tensioning.Rosenbaum...
Steel frames of a building form a lightning protection system (LPS), and the space inside of it is LPZ1. LPZ1 is defined as the space where lightning cannot enter directly and the electric and magnetic fields inside of it can be reduced. In this paper, the contribution of lightning ...

Typical acceptable or unacceptable deformation modes of such buildings under fire are shown in Fig. 2 [2]. For the frames collapsing inside the building (inwards collapse), it can be seen that the resulting deformation will not endanger adjacent property or persons located outside the building ...
