Where to find solved exercises on arches and portal frames

[Clausius2]

I haven't got enough exercises of some course I've failed in July: Structural Engineering. I have to study it again , but I do not have any interesting exercise about arches and portal frames.

Do you know any web link with some of this kind of exercises solved?.

I've tried google, but I've found nothing. Perhaps some university has model exams for this subject, or a collection of solved exercises on line.

Thanks in advance.

Thanks but it's too late. Fortunately I passed the exam the 20th September. I don't want to see more structures never again!
