This book attempts to acquaint engineers who have mastered the essentials of structural mechanics with the mathematical foundation of their science, of structural mechanics of continua. The prerequisites are modest. A good working knowledge of calculus is sufficient. The intent is to develop a consistent and logical framework of theory which will provide a general understanding of how mathematics forms the basis of structural mechanics. Emphasis is placed on a systematic, unifying and rigorous treatment. Acknowledgements The author feels indebted to the engineers Prof. D. Gross, Prof. G. Mehlhorn and Prof. H. G. Schafer (TH Darmstadt) whose financial support allowed him to follow his inclinations and to study mathematics, to Prof. E. Klingbeil and Prof. W. Wendland (TH Darmstadt) for their unceasing effort to achieve the impossible, to teach an engineer mathematics, to the staff of the Department of Civil Engineering at the University of California, Irvine, for their generous hospitality in the academic year 1980-1981, to Prof. R. Szilard (Univ. of Dortmund) for the liberty he granted the author in his daily chores, to Mrs. Thompson (Univ. of Dortmund) and Prof. L. Kollar (Budapest/Univ. of Dortmund) for their help in the preparation of the final draft, to my young colleagues, Dipl.-Ing. S. Pickhardt, Dipl.-Ing. D. Ziesing and Dipl.-Ing. R. Zotemantel for many fruitful discussions, and to cando ing. P. Schopp and Frau Middeldorf for their help in the production of the manuscript.

hi guys, is there any book that explain how EC3 or bs5950 derived? Just like a book like " Reinforced Concrete Design to BS 8110 Simply Explained " from AH ALLEN. Appreciate if anyone of you could recommend me. Thank you.
Le presenti Norme tecniche per le costruzioni definiscono i principi per il progetto, l’esecuzione e il collaudo delle costruzioni, nei riguardi delle prestazioni loro richieste in termini di requisiti essenziali di resistenza meccanica e stabilità, anche in caso di incendio, e di durabilità.
Esse forniscono quindi i criteri generali di sicurezza, precisano le azioni che devono essere utilizzate nel progetto, definiscono le caratteristiche dei materiali e dei prodotti e, più in generale, trattano gli aspetti attinenti alla sicurezza strutturale delle opere.
Circa le indicazioni applicative per l’ottenimento delle prescritte prestazioni, per quanto non espressamente specificato nel presente documento, ci si può riferire a normative di comprovata validità e ad altri documenti tecnici elencati nel Cap. 12. In particolare quelle fornite dagli Eurocodici con le relative Appendici Nazionali costituiscono indicazioni di comprovata validità e forniscono il sistematico supporto applicativo delle presenti norme.

CivilStorm performs a full range of analysis necessary for verification of hydraulic capacity and demonstrating stormwater compliance in complex storm water handling systems. Its dynamic calculation engine handles capacity analysis, detention, looped systems and diversions. Choose the industry-standard EPA-SWMM engine or CivilStorm’s implicit solution.Time saving model management tools such as Scenario Manager, FlexTables, and engineering libraries make CivilStorm both highly cost-effective and extremely flexible. CivilStorm is also fully compliant with US Federal Highway Administration (FHWA) Hydraulic Design Series No. 5 (HDS-5) standards.
Key new features in CivilStorm V8i (SELECTseries 4):
INTEROPERABILITY
Updated support for MicroStation: You can run CivilStorm from within the latest releases of MicroStation V8i (SELECTseries 3). A MicroStation license is required – if you don’t have a MicroStation license, you can choose to run CivilStorm in stand-alone mode.Updated support for AutoCAD: You can run CivilStorm from within AutoCAD 2015 and 2014. An AutoCAD license is required – if you don’t have an AutoCAD license, you can choose to run CivilStorm in stand-alone mode.Direct import of MX Drainage files: The import of MX Drainage files in CivilStorm has been improved, reducing the steps necessary to leverage MX Drainage data.Bentley Map Mobile i-model publishing: This tool publishes a CivilStorm model, including results, for use in Bentley Map Mobile, a free app that works on Android, iPad, and iPad mini tablets.
MODEL BUILDING AND MANAGEMENT
Elevation data assignment: CivilStorm can automatically assign elevation data to node elements, including manholes, using digital terrain models. The node elevation can be updated automatically when the element is moved.Downstream trace: CivilStorm enables the convenient trace and display of the surface water flow direction across any terrain.Redesigned conduit catalog: Conduits with the same section shape and materials are now grouped together in the conduit catalog, making it easier to view and edit them.
HYDRAULICS
Headwall and endwall elements: CivilStorm now supports culvert headwalls and endwalls, which can connect to open channels or closed conduits.Inlet-only hydraulic calculations: Users can now place inlets, check gutter and inlet carryover flows, and adjust the inlet positions as necessary, before designing the pipe network.Storage chambers as pond type: CivilStorm can now model underground storage chamber systems.Improvements to automated design: The automated design calculations for sanitary and storm sewers include a number of enhancements, such as: pipe wall thickness can be included when computing cover; drop structures can be used to minimize cover (previously drop structures only prevented a pipe from exceeding the maximum allowable slope); and a minimum drop depth can be specified for drop structures.
HYDROLOGY
PondMaker: CivilStorm’s PondMaker is an easy step-by-step detention pond and outlet structure design tool.New hydrograph methods: Users can now choose to utilize the ILSAX or time-area hydrograph methods to compute runoff.New loss methods: CivilStorm now allows users to compute infiltration losses using ‘initial loss and constant fraction’ or ‘initial loss and constant rate’ methods.New time of concentration methods: CivilStorm now supports the following additional time of concentration calculations: Kinematic Wave equation, Friend’s equation and Bransby-Williams equation.
