I'm trying to determine the effective throats of some flare-bevel groove welds made between steel plates and steel bar stock.
AWS D1.1 states that the effective throat is 5/16 * (bar radius), or .156 * (bar diameter). However, D1.4 states that the effective throat is .4 * (weld size), which...
We're having issues with some hollowcore planks splitting longitudally between strand. Our hollowcore is 4'-0" wide, with (5) 1/2" strand placed in the bottom. These particular planks are ripped to be 3'-4" wide with (4) strand in them. The pieces are stripped with no problems, but when they get...
Is anyone familiar with a method for calculating the effective debonding of a prestress strand based on its slippage?
The only reference I've found are the strand stress-strain curves, but using these will only let me calculate a prestress loss over the entire length of the member, whereas an...
