And what's the best way to splice 2...
If there are cold joints in the column (for example from different concrete pours at different times (next day)).. and the cold joints are located in area of maximum moment.. what would happen to that region?
Usually.. can you use 4 pcs of 16 mm j bolts embedded 8 inches inside the concrete column where you can attach metal plates on top to support I-beam rafters above it? How do you compute if the 4 pcs of 16mm bolts can take the shear from the wind?
The worker use acetylene to cut excess rebars protruding from a footing. When a rebar is heated by acetylene until it is cut. How much is the thermal expansion of the bars inside the concrete? What is the strain usually? Would it be more than the strain the concrete can handle and would the...
