Abstract
In structural engineering there are different types of duties; amongst them
the analysis part is the most important and crucial part. Because of this it
has been given a great focus. Analysis techniques for most structural
elements with different arrangement of externally applied loads are well
developed and sufficiently covered with modern analysis theories. Further
more, the application of today’s high-speed computers enable the analysis of
complex structures with different load arrangements. In addition to these
effective analysis tools, building design codes provide table of values and
analysis charts for the analysis of different elements of structural systems.
As one of the structural element in building structure, different analysis
methods were proposed for the analysis of suspended slab panel subjected
to uniform rectangular loads.
Among the possible arrangement of externally applied loads on suspended
slab panel a uniform rectangular load is the one which can best represent
the weight of heavy machineries, water tankers, etc. Different simplified
analysis methods were proposed to consider the contribution of this load to
the design action effects. The current practice of accounting these loads in
the analysis of suspended slab panel is to change it to the 'equivalent'
uniformly distributed load. The analysis of regular slab panel subjected to
uniformly distributed load may be carried out using computer soft wares or
using coefficients which are presented in many design codes, the Ethiopian
Building Code of Standards for concrete structures, EBCS 2 – 1995 can be
one example. These methods analysis need to be investigated whether they
can represent the actual load or not.
Therefore, as it is important to address this problem, comparative analysis
has been carried out. A new simplified method which considers the actual
scenario has been developed. This newly proposed method makes use of
coefficients derived from the basic principle of elastic analysis of plate. The
results have been verified by comparing it with results of the finite element
analysis. It enables us to make elastic analysis of suspended slab panel
subjected to the weight of a uniform rectangular load and avoids the
uncertain use of approximate methods.
