Global structural analysis of central cores supported tall buildings compared with FEM
The focus of this article is to present an approximate method of calculation based on the equivalent column theory. This approximate method of calculation may be successfully applied in the case of tall buildings. Knowing the geometrical and stiffness characteristics of the structure, applying the equivalent column theory may determined: the displacements in both directions, the rotation of the structure, critical load, shear forces, bending moments for each resisting element and the torsional moment of the structure. The results obtained using the approximate calculation method will be compared with the results obtained using an exact calculation based on F.E.M.: Autodesk Robot Structural Analysis and ANSYS 12.1.

LPS building: The Hungarian experience
The experience with large‐panel system building in Hungary is reviewed at a time when decisions must be taken about the future of the LPS concept and the buildings that were thereby created. The author describes the models and methods used for structural analysis and discusses the role of different types of abnormal loads in structural behaviour. The paper results from a period spent by Dr Zalka at the UK Building Research Establishment, which has long had links with the Ybl Miklos Polytechnic of Budapest, of which Dr Zalka is now a director.
