Abstract :

In recent years, high-rise construction has been rising. A big challenge for engineers and executives in the construction of these structures is the stability of the structures against earthquakes. And this requires the development of appropriate arrangements for structures under lateral system and are braced system. And this requires the development of appropriate arrangements for structures under lateral system and are braced system. Hence, we decided to evaluate the geometry and arrangement of lateral system for 21-storey of steel structures in two main types do. Also the two groups design 6 model geometry lateral bracing system and mega bracings, with and without consideration of P-delta effect for each of the models we will see this, What role will this effect essentially on the response of structures. And in the end, will have an interpretation of the results.
