RESEARCH ON DESIGN METHOD OF THE KEY JOINTS OF SINUSOIDAL WEB GABLED FRAMES

Sinusoidal web H-shaped members are composed of flanges and sinusoidal webs, and are widely used ingabled frames steel structures because of their higher load-carrying efficiency and better economic benefit compared totraditional flat web members. Based on joint forms of the traditional gabled frames structure, and combined with themechanical characteristics of almost zero normal stress on the sinusoidal web section, the new joint forms suitable forsinusoidal web gabled frames were given. The typical end plate connections considering contact between plateelements were analyzed by using FEA, thus a simplified design method of the connection of sinusoidal web gabledframes was proposed. Both joint details and fabrication requirements of the sinusoidal web gabled frames were alsopresented. Finally, a practical application of the new joint forms in the sinusoidal web gabled frames was given, providing a useful reference for the similar projects joint design.
