DETERMINATION OF MOMENTS IN MUSHROOM STRUCTURES WITHOUT COLUMN HEAD REINFORCEMENT,HAVING VARIABLE SUPPORT HEAD THICKNESS,TAKING ACCOUNT OF THE RIGIDITY OF THE SUPPORTS

ERMITTLUNG DER MOMENTE IN PILZDECKEN OHNE SAEULENKOPFVERSTAERKUNG MIT UNTERSCHIEDLICHER STUETZKOPFDICKE UNTER BERUECKSICHTIGUNG DER STEIFIGKEIT DER STUETZEN

DETERMINATION OF MOMENTS IN FLAT SURFACES,WITH PARTICULAR ATTENTION TO THE STIFFNESS OF THE SUPPORTS,WAS THE OBJECT OF A RESEARCH PROJECT SPONSORED BY THE DEUTSCHER AUSSCHUSS FUER STAHLBETON(GERMAN COMMITTEE FOR REINFORCED CONCRETE)IN 1965.AS THE EVALUATION OF THE MODEL TESTS CARRIED OUT HAS TAKEN LONGER THAN ANTICIPATED,A CONTINUATION PROJECT IS NOW BEING STARTED.THE OBJECT IS TO DETERMINE THE RESTRAINT MOMENTS OF EDGE AND CORNER SUPPORTS IN FLAT SURFACES;AND FROM THESE THE PROGRESS OF MOMENTS IN THE SURFACE ITSELF. THE MATERIAL WILL BE EVALUATED AND SUBJECTED TO ADDITIONAL THEORETICAL CONSIDERATIONS.
