Επιρροή της παραμορφωσιμότητας των πλακών στη στατιστική και δυναμική συμπεριφορά πολυόρορφων κτιρίων

IN GENERAL THE STRUCTURAL ANALYSIS OF FRAME AND SHEAR WALL BUINDINGS SUBJECTED TO EARTHQUAKE LOADINGS, IS BASED ON THE ASSUMPTION THAT THE FLOOR DIAPHRAGMS ARE RIGID IN THEIR OWN PLANE . THE VALIDITY OF THE ABOVE ASSUMPTION DEPENDS ON THE SHAPE OF THE FLOORS. IN THE PRESENT DISSERTATION A PARAMETRIC ANALYSIS IS MADE FOR THE MOST COMMON CASES OF FLOOR SHAPES. THE SCOPE OF THE INVESTIGATION IS THE DEFINITION OF THE BOUNDS WHICH DEFINE THE REGION OF THE APPLICABILITY OF THE RIGID FLOOR ASSUMPTION . FOR THIS REASON THREE BASIC FORMS OF BUILDINGS HAVE BEEN INVESTIGATED, BOTH FOR STATIC AND DYNAMIC EARTHQUAKE LOADING. A) BUILDINGSOF LONG NARROW RECTANGULAR FLOOR PLAN B) BUILDINGS FOR WHICH THE FLOOR PLAN HAS L FORM C) BUILDINGS FOR WHICH THE FLOOR PLAN HAS Π FORM. THE NUMERICAL SOLUTION OF THE BUILDINGS HAS BEEN MADE WITH THE THREE DIMENTIONAL ANALYSIS PROGRAM SAP IV. DURING THE PARAMETRIC ANALYSIS EVERY STRUCTURE WAS SOLVED TWICE I) USINGTHE ASSUMPTION OF RIGID FLOOR DIAPHRAGMS AND II) TAKING INTO ACCOUNT THE REAL FLOOR FLEXIBILITY. THE STATIC LATERAL LOAD WAS APPLIED WITH A TRIANGULAR DISTRIBUTION OVER THE HEIGHT OF THE BUILDING AND WITH A CONTINUOUS RECTANGULAR DISTRIBUTION IN EACH HORIZONTAL PLANE. FOR THE DYNAMIC SOLUTION OF THE STRUCTURES CONSIDERED A MODE SUPERPOSITION ANALYSIS WAS CARRIED OUT. THE RESPONSE SPECTRUM USED WAS THE ONE OF WHICH THE EUROCODE NO 8 PROPOSES.
