This research work is aimed at studyinghe behavior of beam-
to-column connection of pre-aststeel reinforced concrete
structures. The prosndcons of traditional design and
construction ofhese beam-to-column connections are examined
andn innovated method is developed to simplify theonstruction
procedure and to improve its seismicesistance
characteristic. By using a specialesigned cover plate on
the bottom flange oftructural shapes to trasmitted
the forceesisted by the bottom reinforcing bars, it
isound that coupler to connect reinforcing bars inhe
traditional assured.This is demonstrated by aeries of full
size structural testing of beam-tocolumn connections. An
analytical method is alsoeveloped to predict the flexural
strength ofteel reinforced concrete structures and
goodgreement between analytical and experimentaltudy has
been found.
