Hello sepakistan 
i am designing a rafter for structural roof frame, why do we have to haunch the beam? is it the same as the tappered member? how do i calculate the nominal strength of the haunch section? and the eaves and apex connection, does anybody have a design guide with american code(AISC), i found one but it was a eurocode
thanks so much
regards

Certain softwares provide the ability to calculation custom section properties. If you are using RISA3D, you can use RISA Section. If using CSI products, Section Designer is a good option. Haunched beams provide > moment resistance at the ends. 

Thanks.

is there any provision made by AISC? like stability and stuff like how deep am i going to haunch it? because i cant find it somewhere like this one made by eurocode

You should haunch it to the degree such that the minimum requirements of strength and stability are met.

Thanks.

      Assalamualaikum,
      im designing a steel beam. The nominal shear is already meets the requirement which is larger than the required shear force (Vi*Vn > Vu). But my senior engineer said that i have to design an additional stiffener to resist the force when it comes to erection later. How do i design this transverse stiffener considering there nomore shear to resist? is there any provision on AISC about minimum spacing and the thickness of plate required? thanks
