Previous issue date: 2013-06-27 / Through this research is detailed the Brazilian seismic code focused on concrete projects design related to seismic engineering. At the beginning of the research is debated the fundaments of the seismic effects, the influence factors to the
development of seismic effects and also relates the main data registration happened in Brazil. The second step is study the Brazilian seismic code explaining all the concepts related to it and does a compilation to the most important international seismic code. At this research is developed the designing of a building submitted to horizontal equivalent seismic forces and the modal process based on the answer spectrum based
on the brazilin seismic code. It was also developed the design of a commercial building submitted to seismic loads based on the Brazilian code answer spectrum and compared to the same building submitted to wind loads.The research also focus on projects conception and detailing of seismic engineering Project design. At the study of seismic engineering it was concluded that seismic effects require special focus on concrete structures design, proving that is the essential consider the seismic effects / Nesse trabalho s?o apresentados e discutidos diversos crit?rios da norma NBR 15421:2006 para o desenvolvimento de um projeto de estruturas de concreto, considerando a a??o s?smica. Inicialmente fez-se um levantamento dos conceitos
fundamentais da engenharia s?smica, das principais ocorr?ncias, globais e regionais, abordando-se a an?lise dos efeitos geradores de sismos, seus conceitos e particularidades. Apresentou-se posteriormente o detalhamento de todos os
par?metros s?smicos presentes na NBR 15421:2006 e comparou-se com diversas normas s?smicas internacionais. Foi desenvolvida uma compara??o entre edif?cios modelados atrav?s de espectro de resposta e atrav?s das for?as horizontais s?smicas equivalentes, tamb?m se desenvolveu um estudo comparativo de uma edifica??o comercial submetido ao vento e a solicita??es s?smicas. Destaca-se ainda a
apresenta??o das principais recomenda??es e orienta??es t?cnicas em termos de concep??o e detalhamento estrutural que devem servir de condicionantes para projetos atuais. Demonstra-se que os efeitos s?smicos incorrem na necessidade de detalhamentos espec?ficos na estrutura, comprovando-se que a necessidade de uma abordagem diferenciada ? essencial
