Released new version 5.80 of C.S.E..
We have been working at non linear solver to add geometric non linearity (i.e. buckling via non linear analysis, also possibly with material non linearity), and to add contact non linearity (i.e. the bearing surface may be considerered now a problem unknown, when dealing with the fem model of set of components).

JANUARY 2014

The Standing Committee On Structural Safety, SCOSS, (UK) gives notice in its newsletter nr. 34 on April 2014 (page 3) that, following a report presented by Paolo Rugarli, a company in Italy whose advertisements included phrases such as “seismic engineering for all” and “why strain yourself for buildings up to 4 floors”  has been fined for misleading advertising.
The AGCM (Autorità Garante per la Concorrenza e il Mercato, Authority Regulating Market and Competition) fined the company 10,000 euros for “misleading advertising”. As far as is known this is the first time in Italy, and quite possibly anywhere else, that an Official Regulatory Commission has issued a fine for a misleading advertisements related to structural engineering software. The Italian Regulatory Agency has, in addition, indicated that no “absolute validation” of any software is possible.
As SCOSS comments: "As ever the designer must be aware of his or her responsibilities when using software or even books containing formulae. If something goes wrong the supplier/ designer of load tables is not held to account but the engineer responsible for using products is. Checking of software by separate programs or approximate manual calculations is usually advisable, and software cannot replace the engineering judgment of a competent professional. The implication of this Italian ruling in other jurisdictions remains to be seen."

JUNE 24-30, 2012

Trip to Singapore (wow!) and meeting with CSE Asian distributor  Mr Meda Raveendra Reddy. During the 5 days stay in Singapore the program CSE has been explained to Customer Chan W Y Consultants. Besides some demo of the program to possibly interested Structural Engineers have been set up. Presently the number of copies of CSE sold in Singapore are 3.

There has been quite a lot of interest about the program, which is confirmed to be unique as to the generality of the approach to the steel connection checks.

JUNE 2012

Released the paper "La valiunzione del calcolo strutturale", by di Paolo Rugarli. The article discusses some validation activities set up by a University and a Research Company, showing how these validation activities miss quite important features. The paper has been cited by several opinion makers (SEWC, Ordine degli Ingegneri di Milano), and states some very important general rules (validation should be possibly controlled by anyone, should not be a "secret"; it's impossible to validate in an absolute way stating that a program "executes in a reliable way" some computational task as validation may not prove a program to be error free).

MAY 17 2012

Released and available  CSE LIGHT VERSION.

APRIL, 5 2012

The web site has been deeply revised adding more pages, more products, and translating more pages into English.

MARCH, 7 2012

CSE: a first set of 47 English multimedia lessons have been released. Here is the link: CSE ENGLISH LESSONS WITH AUDIO. The light version is almost ready. The scheduled release is by April, 15. There will be a BASE LIGHT version, an ADVANCED LIGHT version, and a PREMIUM LIGHT version. Prices have not been decided yet, but they will be considerably lower than those of full version. The light version is for standard connections only.

NOVEMBER, 22, 2011

CSE FULL version 4.40 released. Very important new features and improvements. The English documentation is ready and available. Version 4.40 is able:
i) to execute elastic-plastic analyses of components;
ii) to build up steel connections using a standard connection database (presently 170 units) so that creation is automatic;
iii) to store new connections in the parametric connection database, by setting up connections parametrically.

Many more new features are not listed here.

New LIGHT version release is scheduled by the end of March, 2012.

SEPTEMBER, 7, 2011

CLASS4 has been released. It is presently in Italian only but it is planned its translation into English. It's a low cost program very helpful for steel designers.

JULY, 2011

The new software program CLASS4, dealing with the effective data computation of typical steel cross-sections, has been completed (presently Italian only). The typical cross sections are: IPE, HEA, HEB, HEM, RHS, Tee, UPN (channels), C, Z, L, W cold formed, with no edge fold, single edge fold, and double edge fold.
The parameterized typical connection database of CSE has reached 150 units.

JUNE, 2011

Added about 90 test schedules referred to the new non linear FEM solver CURAN. Released Sargon version 9.70, with important enhancements of the non linear solver CURAN (truss elements with gap, non linear springs with gap) and with the addition of the effective area computation of the thin-walled cold-formed members, thanks to the general software tool set up one year ago.
An intense developing activity has been ended, aimed at adding very important new features to the software CSE: 1) the ability to create parametric steel joints or parametric steel connections (PRenodes, parametric real nodes); 2) The parameterization of the typical steel joints / steel connections; 3) The creation of a typical steel connections database that can be used allowing the node creation by two clicks; 4) The creation of a CSE LIGHT version, which will be later released: it  will only be able to deal with typical joints (while the full version enables the free creation of joints and connections). We are presently adding typical connections to the database.

FEBRUARY-MARCH, 2011

The new non linear solver CURAN development process moves forward with the addition of the plate-shell (thick and thin) non linear finite elements, and membrane elements. Nonlinear plate elements model will be solved using CURAN by CSE, which will now be able to deal with elastic-plastic analyses of components like angles, plates (base or end), members with work processes, and so on. New validation schedules (about 100) dealing with non linear analysis will soon be added to related the web site section.

SEPTEMBER 2010 - JANUARY 2011

CSE is now fully in English.
New standards have been added to CSE: these are IS 800 (Indian standard) both limit states and working stress, and AISC-ASD and AISC-LRFD 2005, i.e. USA standard both for allowable stress design and for load and resistance factor design.

Agreements have been signed by Castalia srl with NOMITECH (based in Athens, Greece), and with RAM CADDSYS PVT. LTD. (based in India at Chennay). See the distributor page for more detail. CSE will be distributed in several East Countries and in Greece and Cyprus.
JULY-AUGUST 2010

CSE has been extensively used to check the new Mediateca (Media House) in Colle Val d'Elsa (Siena) design by Jean Nouvel, structural design by Ingg. Galluzzi. CSE has been used to check some of the steel connections of this very complex structure.

New features have been added to the program CSE. The English version of the guide has been pre-released (ver. 4.04), and is going to be aligned to version 4.10 by the first half of September.
JUNE 2010

Ing. Paolo Rugarli, Castalia's owner and technical Director, is going to edit the Italian version of the series "Designers' Guide to Eurocodes", originally published by Thomas Telford, London UK.

Ing Rugarli is also in charge of translating into Italian the first book of the series, Designers' Guide to Eurocode 0 EN 1990: basis of structural design, by Profs. H. Gulvanessian, J-A Calgaro, and M. Holicky.
