Connections Study Environment Software Program: a not-standard connection

C.S.E., Connections Study Environment, is a Windows software program completely devoted to the design, study and check of structural steel joints (i.e. steel connections).

C.S.E. has been created thanks to a research and development work, lasting since the end of the 90s (see the history of the project). It is a software package fundamental for Castalia's activity, and is an extraordinary effort as to originality, completeness and innovation. C.S.E. is the result of a far-seeing work, never aimed at the immediate and marketable result, but always directed toward real problem-solving in the field of structural steel connections (or steel joints).

C.S.E. is interfaced with Sap2000TM, STAAD PROTM, STRAPTM, MIDASTM, RISA3DTM and with Castalia's software Sargon, and is its natural completion. C.S.E. is also able to import FEM models and FEM results written in the .SR4 open file format (see link above: Interfacing with CSE). Since the end of the 90s, as already said, we are working to this project, which originally was merely to add a post processor for steel connections to Sargon.

Presently  C.S.E. can work with Sargon or Sap 2000TM, STRAPTM, STAAD PROTM, MIDASTM, RISA3DTM (the fem programs it presently is interfaced with), or as a stand alone tool, and it will surely be interfaced with more software packages, worldwide available (probably also via IFC file format).

The C.S.E. project is very ambitious: instead of developing a program which is able to manage only a given number of possible preset joints (cooking recipes approach), C.S.E. faces the steel connection problem in a very very general way:

aim of the program is to allow the automatic or semi-automatic check of the steel structures joints (connections) which have been defined via a free placement of the components: joined (members), joiners (welds and bolts), and cleats (plates of the most general kind, stiffeners, angles, generic or normalized cross-shapes trunk, like IPE, HEA, HEB, HEM, W, M, WT, UB, UC, UPFC, UA, ASB, UNP, composed, cold-formed, generic... really one of the more than 15,000 cross-section in the archive, or, via SAMBA, any possible composition of these cross-sections).


User's automatic checks can be added to those, very general, performed automatically by the program, for a real customization of the program work.

Built in automatic checks manage a very wide class of joints, and bolts, welds, net-sections, bolt-bearing, punching shear, block-tear, pull-out, sliding in friction joints, and many more checks are fully automatized.

Moreover, on demand, the program is able to automatically create FEM models of components or of sets of components up to the whole node, to run static analyses in linear or nonlinear range, and buckling.

As far as we know, after extended web search, C.S.E. is today the most advanced software platform available dealing with steel connections checks, the only one allowing free placement of components and the successive check of generic joints, not based on cooking recipes.
