Overview
SAFE system
Slab systems are a very special class of structures. They arecharacterized by
their simplicity in geometry and loading. They are typically composed of
horizontal plates supported vertically by beams, columns and walls. The loading
in general is comprised of vertical point, line and surface loads. Basemats
share the same characteristics as those of elevated slabs, with the exception
that basemats are supported on soil and loaded by columns and walls. Most
commercially available finite element programs can be used to model slabs and
basemats. However, such software packages do not recognize the unique
characteristics of slab systems, resulting in excessive solution times and
significant loss of productivity and man-hours. Also, such packages are
difficult to use and are not integrated with slab design algorithms that will
produce information directly usable by the structural engineer.
Recognition of this problem, nearly two decades ago, led to the development of
the SAFE System based upon the finite element method. SAFE is special purpose
software that automates the analysis and design process for the structural
engineer, lending greater sophistication to the engineering of slab systems. It
is designed to minimize engineering manhours and processing time associated with
the design of concrete slab systems. SAFE is a completely integrated product
that operates within the Windows95/NT environment. It features a powerful
graphical user interface unmatched in terms of ease-of-use and productivity.
Creation and modification of the slab model, execution of the analysis, checking
and optimization of the design and production of graphical displays of the
results are all controlled through this single interface.
The SAFE program will analyze and design slabs of arbitrary geometry including
drop panels, openings, edge beams and embedded beams subjected to vertical point,
line or surface loads. Column supports, wall supports, or soil supports for
basemats can be modeled. Discontinuities in the slab system, due to slip joints
or differences in slab elevations can be included. The slab is modeled with
orthotropic plate elements. The beam element allows for bending, torsion, and
shear deformations.
About Developer
Developer : Computers and Structures, Inc. (CSI)
Providing software solutions for structural and earthquake engineering.
Founded in 1976 by company President Ashraf Habibullah, CSI is recognized
worldwide as an innovative leader in the development of software tools for the
analysis and design of civil structures. CSI products are licensed to thousands
of structural engineering firms throughout the USA and in over 60 foreign
countries.
The development of CSI software spans three decades, starting with the research
of Dr. Edward L. Wilson at the University of California at Berkeley. The
revolutionary SAP program was first released in 1970, and Dr. Wilson has
subsequently been recognized by national and international engineering societies
as one of the preeminent researchers in the field of computer aided structural
analysis.
Each of CSI's programs is tailored to specific classes of structures, allowing
the engineering community to work at more productive and efficient levels than
is possible with "general purpose" type programs. SAP2000 is intended for use on
civil structures such as bridges, dams, stadiums, industrial structures and
buildings. ETABS has been developed specifically for multi-story building
structures, such as office buildings, apartments and hospitals. The SAFE System
provides an efficient and powerful program for the analysis and design of
concrete slabs and foundations.
Not only is CSI known for analytically sophisticated software, but for
unsurpassed product support as well. User support activities include advice on
structural systems, interpretation of structural behavior, clarification on
various aspects of building codes, opinions on special modeling problems, and
other aspects associated with the subject of computerized structural analysis
and design.
