REVIEW ON DYNAMIC ANALYSIS OF PSC T BEAM & BOX GIRDER BRIDGESUPERSTRUCTURE FOR DIFFERENT SPAN LENGTHS

Civil Engineering

The pre-stressed concrete bridges have excellent riding characteristics that minimize traffic vibrations, torsional rigidity, less likely to crack prematurely continuous span, strength and the most noteworthy characteristic is natural frequency of vibration hardly matches with vehicle frequency therefore attained spacious acceptance in freeway, highway flyovers, and in modern metro rail systems. As bridges are the important structures should be capable to withstand static as well as dynamic loads specially, earthquake-induced load to achieve a structure that behave at the level of life safety under enormous earthquakes. The present article shows the linear dynamic behavior of T-beam girder and Trapezoidal box girder bridge deck and compares static as well as dynamic behavior
