RESONANCE IN THE EXTERNAL VIBRATION OF CONCRETE

LA RESONANCIA EN LA VIBRACION EXTERNA DEL HORMIGON

A STUDY IS PRESENTED OF THE VIBRATION OF FORMWORKS, AND ATTENTION IS DRAWN TO THE FACT THAT, UNDER FULL-MOULD CONDITIONS, RESONANCE NEVER OCCURS IN MEMBERS WHICH, FROM A STATIC POINT OF VIEW, ARE SATISFACTORILY DESIGNED; BUT THERE IS ALWAYS A MOMENT OF RESONANCE DURING THE FILLING OF THE MOULD. BECAUSE OF THE OCCURRENCE OF THIS RESONANCE, SPECIAL PRECAUTIONS MUST BE TAKEN DURING THE INSTALLATION OF THE VIBRATOR, ITS UTILIZATION AND EVEN ITS SELECTION. THE DIFFERENCES BETWEEN PNEUMATIC AND ELECTRIC VIBRATORS ARE CONSIDERED TOGETHER WITH THEIR POSSIBILITIES OF USE.
