Analysis of High Raised Structures in Different Seismic Zones with Diagrid and Shear Walls Using E-Tabs

The rapid growth 0f urban population and limitation 0f available land, scarcity and high cost 0f available land, the taller structures are preferable now days. Tall structures have fascinated mankind from the beginning 0f civilization. The Egyptian Pyramids, one among the seven wonders 0f world, constructed in 2600 B.C. are among such ancient tall structures. Such structures were constructed for defense and to show pride 0f the population in their civilization. The growth in modern multi-storied building construction, which began in late nineteenth century, is intended largely for commercial and residential purposes. But, from a structural engineer's point 0f view the tall building or multi-storied building can be defined as one that, by virtue 0f its height, is affected by lateral forces due to wind, earthquakes, machinery vibrations and some other sources 0f vibration that cause structural damage or even collapse 0f the structure and they only play an important role in the structural design. The design 0f tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. The design criteria are strength, serviceability, stability and human comfort.
