EARTHQUAKE RESISTANT REINFORCING STRUCTURE OF TRUSS FRAME

摘要

PROBLEM TO BE SOLVED: To reduce burden axial tension of a truss member in an existing or newly constructed truss frame. ;SOLUTION: Installing pieces 1 and 1 are fixed to a nodal point on the upper surface side of a frame and a nodal point on the under surface side of the frame except a nodal point positioned under its nodal point, and a tension member 2 is installed between both installing pieces 1 and 1. A bundle member whose lower end projects from an under surface of the frame is arranged through the nodal point on the upper surface side of the frame and the nodal point positioned under its nodal point, and the installing pieces 1 and 1 are fixed to a lower end position of this bundle member and the nodal point on the upper side of the frame except a nodal point of an upper end position of its bundle member, and the tension member 2 is installed between both installing pieces 1 and 1. Tensile force is introduced to the tension member 2.;COPYRIGHT: (C)1997,JPO
