In this paper of works will be try to present the fundamental computation referring to the imperfection impacts phenomena of non-precise erection effects of the structural members as are vertical columns. Depends from the structural type, the structure should have a vertical structural members with the enough vertical and shear capacity provoked from horizontal action of earthquake, wind, dead and imposed vertical loads. The structural designers, during the structural computation are improve the several approximations creating the dynamic modeling, having into the consideration of structural elements classification in the prior and secondary structural elements. It is very none that the structural vertical elements have a designed capacity from the horizontal actions, the nonstructural elements has the indirect impact on the structural behavior at all. Also the non-precise erection phenomena or imperfection of the vertical structural members is very important in the structural behavior.

A big research effort has been made on the prediction of earthquakes in the last decades, and in fact the exploration of the new techniques aiming to foresee the occurrence of seismic events is in a continuous progress. Several analytical tools have been developed around the world in order to estimate, with different degrees of accuracy, the vulnerability of buildings and the probable loss of lives and economic resources, due to the occurrence of an earthquake. Those tools are intended to be used by government agencies, and even by insurance companies, as a mean for planning of emergency preparedness procedures and response strategies, and also for the reconstruction phases. Nonetheless, most of the current available tools require a large amount of resources, in terms of money, time and computational effort, in order to be properly implemented and effectively used. The paper presents the basic requirements and procedures for the seismic design of Reinforced Concrete Structure of buildings with non-connected shear walls according to the European Code for Seismic Design of Buildings, Eurocode 8. For the many cases, lifelong and Sustainability of the Structure are depends from the earthquake action, type of structure, quality of materials, height, shape of building etc. Based on devastating effects data from the earthquake strike in recently time for the all around and South East European Countries the Structural type has a prime role for the building capability. Type of structure with structural members shear walls are most sustainable for the resistance of horizontal forces coming from earthquake strikes. The treatment of those structural members such are the shear wall their shape, methodology of reinforced have been give a good performances in capacity of Structure. In the height story buildings the usability of shear walls are very preferable because in one side they are decrease the horizontal deformation.
