Overview
CP&A offers a series of commercial software packages for quick and
efficient structural design of material handling equipment of all styles
and types. In addition, we offer
SEC2000, a general purpose, stand-alone program for calculating
engineering cross-section properties of complex shapes. For seismic
design, we offer custom time-history analysis software that integrates
with SAP2000NL.

CP&A's
structural design software allows an engineer to efficiently
design cranes and other load handling steel structures.
These programs are available for purchase by manufacturers and
engineering firms that wish to optimize designs or review designs prepared by others.
Several
structural software packages are available. The base package
includes CPA/STRESS and an
accompanying set of CPA programs. Add-on optional packages to
this base package include CPA/FATIGUE
and CPA/BUCKLING.
The software is
Windows compatible and runs on laptop or desktop PC's. The finite
element module is SAP2000. Stress calculations are performed
automatically for governing load cases, for user defined loads and
load combinations. Thin plate buckling and fatigue calculations
are also performed automatically and conform to all the commonly
used design specifications such as FEM, BS, DIN, CMAA, and JIS.
Extensive graphics are used to verify that input data is correct.

Mechanical
|
Mechanical calculations can be tedious, time consuming, and
subject to mathematical error. All of our mechanical
calculations are done by Excel spreadsheet. Through
automation of the mechanical design process, these programs
can be used to quickly and accurately determine the hoist,
trolley, boom, and gantry mechanics for the container cranes
or any other material handling equipment that we design.

Section
Properties |
SEC2000 is a standalone powerful
section property calculation program. You can combine plates,
shapes, pipes, arcs, and arbitrary shapes to define a cross
section. SEC2000 calculates area, center of gravity, moments of
inertia for the cross section, and also calculates section modules
at your defined points. The program is fully parametric, so you
can use constants or define variables to use in expressions that
locate and size the plates, pipes, arcs, and arbitrary cross
sections. Sections are stored in libraries. You can define
templates for others to use and make libraries of
sections and/or templates so you can standardize your engineering
calculations. Printed output includes input data and typical
calculated cross section properties, as well as a scaled graphic
of the section including axes and labels. File output includes
ability to custom format the calculated data for use by many of
the leading FEA programs, like SAP2000, Algor, Ansys, and others.

Non-Linear Time History
Design of Members and Connections |
One of the problems encountered in
non-linear time-history design is the amount of data produced by the
FEA package. THAnalysis allows the user to define design
algorithms for checking members and connections. The user
creates a script file with full variable definition and expression evaluation at each time
step. For large seismic upgrade or rehabilitation projects, this
program has been shown to save a significant percentage of the construction
costs. For new design, depending on the design philosophy, typical
weight savings would be on the order of 5% to 10% of the lateral force
resisting system. Since the design algorithms are fully user-defined,
the program can be tailored for any materials (concrete, steel,
composite), any code, and any connection configuration. The
entire structure, members and connections, are evaluated at each of
the individual time steps used to define the seismic event.
