SAM-LEAP5 provides scope for 2D and 3D framework and
finite element analysis through the same graphical user
interface utilised for section and beam design. This
enables seamless integration of the analysis and design
modules.
A wide range of bridge decks and substructures can be
modelled using; line beams, plane frames, grillages,
space frames, shell finite elements and combined beam
and finite elements for composite construction. Typical
examples include; solid and voided slabs, composite beam
and slab, box girders and cable stayed bridges.
The graphical drawing tools
provided enables the easy creation of bridge decks and
substructures. A facility to import structure geometry
data from third party Computer Aided Design (CAD)
software is also included. Sections and beams can be
defined and associated with the analysis model, so that
the program automatically calculates the section
properties used in the analysis.
Line beam analysis is very
useful for determining dead weight effects, as well as
secondary effects due to shrinkage & creep and
differential temperature.
A comprehensive range of
advanced modelling tools is available. Some of these
include;
non-linear facilities for tension/compression only
members, lift-off supports, member limiting forces(e.g. plastic hinges), support reaction limits (friction modelling), visual staged construction analysis, 3D post-tensioning cables, calculating losses and
secondary effects.
The general
loading library provides scope for representing a
variety of permanent loads and live loads. Some of these
include; joint loads, member point loads, uniformly
distributed loads, linearly varying loads, hydrostatic
loads, patch area loads, temperature loads, pre-stress
loading, distortion loads, and customisable vehicular
loads. Intelligent routines are available for the
creation of load combinations and envelopes.
Flexible and comprehensive reporting of input data and
results output both graphically and in tabular format is
available. The resulting design load effects, e.g.
maximum bending moments and associated shears, can be
transferred directly to the beam design modules for code
checking.
Vehicle Load Optimization
For the analysis of live load effects, influence lines and surfaces can
be produced for a variety of design details such as bending moments,
shears, torque and reactions. This enables automatic creation of basic
vehicle loads for both road and rail at the most critical locations.
The advanced vehicle optimisation facility enables the analysis of
multiple influence load positions, in order to determine the most
critical combination of basic loading patterns. The program
automatically produces the critical vehicle positions, intensities and
combinations in accordance with a variety of international design
standards. This process takes a fraction of the time compared with
conventional load enveloping methods.
