Apparatuses connecting and reinforcing connection structural members at crossing-joint along multiple ways are disclosed, which is featured by the design detailing for a class of combinations that includes V-shaped Craters, pm or tendon that goes through the crater, and additional V-shaped sockets and V-shaped shear keys. Whereby the key idea is to smear out high stress concentration within localized area by the detailing to achieve asymptotic contacts between major force-carrying members, local reinforcements by V-shape featured detailing, and a uplift mechanism to utilize internal forces such as posttension and gravity to keep structural integrity when these forces loss beneficial unction under extreme load conditions.
