Beam is not properly bonded to shell/solid

Hello there,

I have been working on weldments from last 1 months but whenever I started static analysis in solidworks,it gives error like"Beam is not properly bonded to shell/solid".

In my assembly,it contains solid parts and beams,

I tried creating contact sets but it didn't work.

I have attached the pic of whole assembly and second one is where I give load to the assembly.

Pls ans if anyone knows the solution.

thank you
