WebNov 7, 2001 · Welding of grade 431 stainless steels is difficult due to the chances of cracking. It is recommended to pre-heat the materials to 200 - 300°C before welding, and carry out post-weld heat treatment at 650°C. Welding can be performed using grade 410 filler rods, but ductile welds can be achieved using grades 308L, 309 or 310 steels.

Webto the vibration measurement method and due to the damping evaluation method. In Japan, 1st mode damping ratios are used 2.0% in high rise steel buildings and 3.0% in reinforced concrete buildings in the design stage such as earthquake or wind action. And relations in the damping ratios of lower modes are proportional to natural frequencies. WebDifferent structural damping ratios of 0.05, 0.10, 0.12 and 0.15 for the massless foundation input model and 0.05 for the viscous-spring boundary model are assumed and compared. The distributions of the damage variable, i.e., stiffness degradation, d, of the dam are shown in Figs 12.11 and 12.12.
