"
Steel Connection Analysis", Paolo Rugarli John Wiley & Sons  Oxford, 2018
This book is about steel connection analysis. The matter is exposed using an innovative approach. The book describes how the checks of the connections between steel members
(bolted and welded), can be faced by general methods. The book is the outcome of a research started at the end of the 90s (see CSE).
The chapters are: 1. Introduction 2. Jnodes 3. A model for connection 4. Renodes
5. The pillars of connection analysis 6. Connectors: weld layouts 7. Connectors: bolt layouts and contact 8. Failure modes 9. Analysis: hybrid approach
10. Analysis: pure fem approach 11. Conclusions Appendix 1: conventions and recalls Appendix 2: tangent stiffness matrix of filletwelds Appendix 3: tangent stiffness matrix of bolts in shear

Journal of Constructional Steel Research, 65, 15971606, 2009
This paper, published in the important peerreviewed international magazine JCSR, explains the research work
done (in 1993) about the crosssection classification problem, and the "reclasses" classification
method, proposed by Paolo Rugarli.

"Prediction of the load carrying capacity of slender crosssection members under eccentric axial load. Part 1: the approach",
Claudio Bernuzzi, Paolo Rugarli
Costruzioni Metalliche, JulAug2009 (English)
This paper presents a new method to compute load carrying capacity of thinwalled, coldformed crosssections. The paper also discusses the current EN
199313 approach.
▶
"Prediction of the load carrying capacity of slender crosssection members under eccentric axial load. Part 2: validation",
Claudio Bernuzzi, Paolo Rugarli
Costruzioni Metalliche, NovDec2009 (English)
This is the second part of the previous paper, where results got are compared

"Simplified formulae to flexural and lateraltorsional buckling checks according to Eurocode 3 (EN 199311), Method 2", Paolo Rugarli
Acta XXII Congress CTA,
Padova, September 2009
This paper presents an alternative way, very useful, to write the formulae for flexural and lateraltorsional buckling checks as required by Eurocode 3.
▶ "Zones, Grids or... Rooms?", Paolo Rugarli
Ingegneria Sismica, 1/2008
This paper examines the new Italian seismic standards rules (NTC 2008) to determine design spectra. The paper
shows that the standard had several important problems of application, and that the precision required by this
standard is completely illusive. The "roomeffect", that is the abrupt up to 20% change of design PGA from one
room to another of the same flat  due to clear errors in the standard , is here acknowledged for the very first
time.
▶
"Limit states load combinations: the untold of the standards", Paolo Rugarli
Ingegneria Sismica 2/2004
This important paper shows that the combination rules used by the Italian standard and by Eurocodes
embed not safeside assumptions. The paper is a critic to the presently adopted way to apply Load and Resistance Factor design (limit states).
▶ "Le magnifiche sorti e progressive", Paolo Rugarli
L'Edilizia n° 133 (2004)
This paper refers to the previous one, disclosing to a wide public its main results. It also reconnects
to the public debate which followed Italian Ordinances 3274/2003 e 3316/2003, issued by Silvio Berlusconi's Prime Minister office.
▶ "In margine all'Ordinanza 3274", Paolo Rugarli
Ingegneria Sismica, 3/2003
This paper has been published by the Italian technical magazine Ingegneria Sismica, and clearly enumerates several technical reasons why Ordinance 3274 must be criticized.
▶ "Riflessioni e osservazioni sulla nuova Ordinanza 3274", Paolo Rugarli
Il Giornale dell'Ingegnere n°18/2003, pagg 89
This paper was published by "Giornale dell'Ingegnere" and as well as the previous is critic toward Ordinance 3274.
The paper was one of the very first public act to criticize the standard which was later amended by 122 modifications.
▶
"Software di calcolo", Paolo Rugarli
Manuale dell'Ingegnere "Colombo", 84^ed., Hoepli
This work, written in October 2002, is an overview of the problems related to structural software use: the reliability, the errors, the
conversion of a standard into a software program, the mutual relationship between who writes the Law, the Software Developer, and the User.

"Elastic and Plastic Flexural Properties. Automatic computation of generic crosssections", Paolo Rugarli
Costruzioni Metalliche, 4/1998 (link to English version)
This paper describes a general method to compute elastic and plastic flexural properties of generic crosssections.
The methodologies shown in the paper are used by all the programs of Castalia, and namely by the program SAMBA.

"La classificazione secondo Ec3 dei profili ad I sottoposti a sollecitazioni miste, Paolo Rugarli
Acta Congress C.T.A., October 1993
This method is used by the automatic Sargon. automatic Eurocode 3 checker.
The paper is important because it shows that yet in 1993 problems due to the real applicability of the formulae
to classify crosssections according to Eurocode 3 were pointed out. The paper deals with axial force plus biaxial bending
stress states and proposes a method which almost 20 years later has been published in JCSR (see above).

"Software orientati alla comunicabilità ed al controllo dei dati nella ingegneria delle strutture", Paolo Rugarli
Acta Congress C.T.A. October 1991
This paper was written at the beginning of Castalia activity. It pointed out some important problems and issues in structuralsoftware development at that time.
