As part of the intervention of “Redevelopment of the harbor and construction of a pedestrian bridge in Bellaria Igea Marina ” we performed the analysis of the original design in order to propose improvements to the project. The objective is to” oost ” the effectiveness of the design choices improving its performance. Having fulfilled the mode of action, we have analyzed the improvements to be the method of implementation of the work, and to the integrative planning proposals and improvements. More specifically, since the effects of the seismic structure depend on the plan distribution and elevation of the masses and stiffness , as well as the strength and ductility of structural elements, we defined variations without substantial changes to the original project that retain flexibility as to avoid having to change the choice of the structure factor “Q” already adopted in the project the characteristics of regularity in plan and height can be kept.
