STUDY ON PERFORMANCE OF A NEWLY DEVELOPED BRIDGE RAILING USING EXTRUDED ALUMINUM-ALLOY POST

Abstract

 A new type of post for the bridge railing has been developed using the extruded multi-hollow-type shape of aluminum-alloy to have the improved landscape and permeability. First, static tests and numerical analyses simulation have been performed using model posts made from aluminum alloy plate to determine the multi-hollow-type sectional dimensions. Then, extruded posts have been tested and analysed to prove the performance following the code for the design of the railing in Japan. The new type of post can be used for different strength types of bridge railing changing the width when cutting the extruded member.
