(2) The Analysis of Grid Frameworks and Floor Systems by the Electronic Computer

The generalised slope-deflection method of structural analysis is now quite well-known and is particularly suitable for the electronic computer solution of rigid jointed frameworks. It was used for the analysis of plane frameworks by Livesley,who went on to develop his basic computer programme to include for automatic design and elastic instability. There is no theoretical difficulty in extending the method for the elastic analysis of any space structure, with the following variations allowed in the members, if applicable:- (i) variable sections, (ii) curved or bent centre-lines, (iii) rigid, pinned or elastically-restrained connections. It is also possible to include for the effects of:- (iv) shearing, twisting, axial and bending deformations (v) elastic supports along the lengths of members, (vi) force, moment and torque loadings, (vii) settlements and temperature changes.
