Abstract

The main loads acting on any bdding ate the vertical and the lateral loads. Lateral loads are
induced mainly from the wind and the earthquakes and should be considered in the design of
reinforced concrete structures, especially for high-rise buildings. Great modifications were
introduced to the previous Egyptian code of practice for calculating loads and forces in structural
and building works 1993, ECOP-93. The new Egyptian code ECOP-201, 2003 introduced the
method of spectrum analysis for calculating seismic loads instead of the previous simplified
method. In many cases effects of earthquakes are found to be dominant and more critical than
wind effects. This depends on sonie factors defined by the codes. In this research the latest code is
reviewed for wind and earthquake analysis and discussed to show all factors affecting the design.
A computer program is developed to analyze the structural buildings subjected to wind pressure
and the equivalent loads of earthquakes defined by the two Egyptian codes. Numerical examples
are solved, analyzed discussed and compared for different factors. The main conclusions are
summarized
