General technical features (excerpt)
|
Fem model creation inside the program. Import of fem models in the Sargon or Sap2000
file format. Automatic recognition of members. Automatic recognition and catalogue
of equal jnodes according to very general rules. Creation of a listing
of jnodes set
and their features, including internal forces envelopes, at different instances of the jnode
and at different load combinations. Capability of transforming a jnode into a re(al)node
thanks to component addition, like angles, double angles,
rectangular plates, beveled rectangular
plates, stiffeners, triangular plates, trapezoidal plates,
regular polygon plates, circular
plates, irregular polygon plates, generic cross-section trunks, considering more than 10,000
cross-section shapes available into the Samba database (IPE, HEA, HEB, HEM,
UNP, T, L, C, welded and rolled, T cut from H and I rolled, angles, CHS, RHS, cold formed,
composed, et cetera), constraint blocks. Copy, rotation, move operation applied to objects.
Capability of defining workings like generic shape cut-outs (via cut-polygon or box),
face rotations, face translations, bevels (square, circular, triangular).These workings
can be applied both to members and throughs. Members trim and extend. Capability of defining
bolt layouts with rectangular matrix and staggered positions,
circular layouts, or completely free
placement of single bolts in bolt layouts. Shear only bolts. Tension and compression or just tension bolts.
Anchors, friction joints, no slip bolt layouts. No-tension bearing surface bolt layouts
(non linear computations to find neutral axis and compressed area of bearing surface). Supports
with no-tension linear and non-linear constitutive law, elastic perfectly plastic, trilinear,
parabola-rectangle. Bolts can be applied to any plane face of any object in contact with other objects,
that will be bolted to this one (parallel faces). No limitation of placement, orientation, inclination.
Capability of defining fillet weld layouts, between plane faces in contact, with arbitrary weld number
and position. Penetration weld layouts (full or partial). Capability of defining component local axes as current reference axes.
Capability of defining user variables and conditions thanks to formulae saved by the program
(no programming skills required), starting from pre-defined variables including data
referring to the components in the scene (for instance a variable mikey= m2.fy / m2.ft or
a condition N< m1.fy * m1.A / gM,0). Automatic recognition of connections, with no need to select the relevant objects.
Renode automatic connectivity and topology recognition, overlapping automatic check.
Ill connections, unconnected components automatic check. Automatic reconstruction of all
connecting chains from a master member to a slave member, or from a master to a constraint block, or,
in central jnodes, from a member to central through (hierarchick jnodes, constraints, central jnodes).
Automatic checks of all load combinations defined into the fem model, or, as well,
automatic checks based on elastic and plastic limits of members, properly factorized
(no need of an external fem model to check joints). Joiner checks according to
allowable stresses CNR, limit states CNR, Eurocode 3 part 1-8 (EN 1993
1-8) where applicable (bolt
and weld checks, upsetting checks, et cetera,). Automatic creation of fem models of components
for static solver CLEVER (embedded) or for SAP2000TM. Models are
meshed
automatically with the desired mesh size. They include elementary actions transferred
by single bolts and welds to the component. Component fem model allows a careful check
of stress state when needed. FEM models apply to components with cut-outs and bevels, as well.
Automatic upsetting checks for all pieces connected by bolts. Automatic slip checks for friction bolt
layouts. Pull-out of anchors automatic checks. Automatic surface bearing check in surface-bearing
bolt layouts, compressive stress display in bearing surface and tension stresses in bolts.
Automatic search of net cross-sections in members (due to bolts, or cut-outs).
Net section automatic
simplified checks (axial force plus biaxial bending). The axial force and bending acting at a given net cross-section
are computed by adding single contributions of bolts and welds (stress diffusion).
Normal stress display in net sections. Automatic simplified checks of throughs in their proper sections,
using beam-like cross-section resultants applied to proper subcomponents cross-sections.
Renode displacement checks. User checks based on user-defined checking rules, stored by the
program and then applied. The program can thus be fully customized, extended,
automatized.
False colour display of exploitation factors of each component being checked (including user checks).
Displaced display of renode for a full understanding of its working mode.
Display of exchanged forces between each component with the others, and so equilibrium
re-construction and internal forces flow clearly explained. Creation of an extended listing
with the results of all checks, and with computing data of all components. English and Italian.
User measure units (also different from those actually used by analyst: they can be changed at any time).
Export of DXF files with the 3D model of the renode (FACE3D).
Capability of upgrading renode model, saving the work done, after changes in the original fem model (if any).
