Investigation of Tensile Strength of Welded Splices of Steel Bars

Due to the increasing need to use rebar in construction, many efforts have been made to optimize its use. One way to reduce rebar usage is to use welded splice instead of overlap splice. However, the Iranian Concrete Code only refers to the welded splice generalities and there are no rules on how to...
