Seismic-resistant steel structures are designed to dissipate the earthquake’s incoming energy by means of plastic deformations in ductile elements (i.e., beams, braces, and links, depending on the structural type) [1,2,3]. However, the repair costs in the aftermath of a severe earthquake ar...
A tightening procedure may be finished or completed once the bolts have been tightened to a threshold level of torque. As described herein, a torque wrench may be used to determine that the threshold level of torque has been met for a given tightening bolt. One of ordinary skill would apprec...
The tightening procedure involved: (i) initially applying a torque of 400 N·m to the bolt head using a torque wrench while holding the nut to prevent its rotation with another wrench, followed by (ii) a 180-degree rotation of the bolt head using a pneumatic wrench. This approach, ...
Primarily, the design procedure quantifies the capacity of the corrugated aluminum shell and reinforcing ribs to resist bending moments. Alumnium Box Culvert installation MpH MpC (Mp) (Mp) Due to the indeterminate nature of the structural elements, finite element analysis was developed to evaluate ...
For example, the truss assembly can be moved up or down along the structural adjustment sleeve to a desired height and then locked at that height by placing a bolt through the truss connection plate 4C into one of the holes in the structural adjustment sleeve 3 that is at a desired level...
