RE: Balustrade Design
reading the above, you shoulfd have a full set of calculations to cover the design anyway, what did you recieve from your engineer, any calculations? these should detail all you need. i get the feeling we are all directing you in the coreect direction, a little knowledge is dangerous! we have people asking similar questions every working day, only giving part of the information and looking for the answer, we have to protect them from dangerous design. we are all responsible engineers and have a charter to adhere to. if you realy want to get an insight into the subject, there are lots of good books covering the basic of design available from technical book shops.
