Discussion on Comfort Level of Long-span Steel Truss Footbridge
摘要
Abstract
This paper analyzes the constraint conditions,truss height,sidewalk location,truss rod section size and other factors of long-span steel truss footbridge,selects the most sensitive factors affecting the natural vi-bration frequency of footbridge,and optimizes the design scheme based on the actual situation.However,when the natural vibration frequency of footbridge does not meet the relevant Chinese regulations,through the analy-sis of international mainstream norms,it is found that the German code has strong operability and wide applica-bility,so the comfort analysis of long-span steel truss footbridge can be carried out according to the German code.In the case of not meeting the comfort requirements of the German code,the damper design is carried out,and the design prospect of frequency modulation bridge panel is put forward.关键词
