The diploma deals with the seismic design of reinforced concrete structures according to SIST EN 1998-1. In the first part of my work we discuss about designing, dimensioning and constructing of reinforced concrete frameworks with ductility class medium. The second part of the work, indicated as a supplement, describes the procedure of calculation made with multi-modal response spectrum analysis on footpath. The process of calculation for period of forms, period of times, seismic forces and movements was made in SAP programme, which was used in the diploma
