Is this Truss structure been analysed correctly, please comment on the member release and support fixity and bracing.

Please find the truss shed file attached for the consideration

as per the requirements and to remove instabilities and excessive deflection I have put redundant bracing and supports made fixed and some members chnaged from truss member to beam.

Please check and comment on the structure.

Thanks in advance.Prorva - Sand & Gravel Storage.std
