Part B:
Analysis & Design
of Concrete and Steel Structures
B1. Introduction
In “Part B” single members, plates and three-dimensional frames are addressed employing
elastic linear static analysis. The analysis is based on the finite element method (FEM),
using beam elements (according to Euler–Bernoulli theory and considering elastic stiffness
for the concrete members) and/or shell elements (plate & disc action simultaneously) with
six degrees of freedom at each node.
A series of test problems (examples) have been analysed to test the various features of the
program and demonstrate its adequacy in several applications. For each example, a short
description of the problem and the tested technical features of the program are presented in
addition to the comparison of results obtained from ScadaPro software and from other
computer programs.
To validate and verify ScadaPro, the test problems were run on a PC platform that was a HP
machine with Intel Core i5 Processor and 6 GB of RAM operating on a Windows 7
operating system.
Concerning acceptance criteria, the comparison of ScadaPro results with results obtained
from other computer programs is represented by the percentage difference evaluated by the
formula

Difference

=
. This difference is
typically characterized in one of the following three ways:
•
Exact:
There is no difference between ScadaPro results and results obtained from
other computer programs and bibliography.
•
Acceptable:
Concerning displacements of structures, the difference between
ScadaPro results and results obtained from other computer programs and
bibliography does not exceed five percent (5%). For internal forces values, required
reinforcements and maximum degree of utilization of steel sections, the difference
does not exceed ten percent (10%). Concerning comparison with experimental results,
the difference between ScadaPro and other programs and bibliography does not
exceed twenty five percent (25%).
•
Unacceptable:
Concerning displacements of structures, the difference between
ScadaPro results and results obtained from other computer programs and
bibliography exceeds five percent (5%). For internal forces values, required
reinforcements and maximum degree of utilization of steel sections,, the difference
exceeds ten percent (10%). Concerning comparison with experimental results, the
