A cantilever riverside boardwalk has been opened to the public as shown in Figure Q.3; however, it was found that the structure experiences significant human- and traffic-induced vibrations. A harmonic oscillation test found the natural frequency of the structure to be 2.25 Hz. It is proposed to retro-fit braced struts at 5m spacing so that the natural period of vibration will be 9 Hz, Given that E= 200 kN/mm² and ignoring buckling effects, determine the required area of the strut. 1 m. 4 m A B 100 kg/m² PROPOSED STRUT PIN 4 m
