Global Structural Analysis of Buildings

Global Structural Analysis of Buildingsis a practical reference for professional civil and structural engineers in construction firms, consultancies, and building research organisations. The theoretical aspects of the book will appeal to postgraduates, lecturers and reserachers of structural analysis and design.

Karoly A. Zalka is Visiting Professor to the Technical University of Budapest, Hungary.
