DISTRIBUTION OF LONGITUDINAL HORIZONTAL FORCES AMONG BRIDGE SUPPORTS

A METHOD IS PRESENTED FOR ANALYSIS OF THE DISTRIBUTION OF LONGITUDINAL HORIZONTAL FORCES ACTING ON THE BRIDGE SUPERSTRUCTURE AND THE EFFECT ON THE BRIDGE SUPPORTS WITH RESPECT TO A POINT OF ZERO-MOVEMENT. THE ANALYSIS CONSIDERS THE ACTUAL STIFFNESSES OF INDIVIDUAL SUPPORTS AND THEIR INFLUENCE ON THE LOCATION OF THE POINT OF ZERO-MOVEMENT, WHICH DOES NOT NECESSARILY COINCIDE WITH THE POSITION OF ANY OF THE SUPPORTS. THE POSITION OF THIS POINT OF ZERO-MOVEMENT HAS A DIRECT INFLUENCE ON THE MAGNITUDE OF HORIZONTAL FORCES INDUCED AT THE TOP OF THE SUPPORTS. THE METHOD ANALYZED TAKES INTO ACCOUNT ALL POSSIBLE EXTERNAL AND INTERNAL FORCES, E.G., TEMPERATURE, CREEP, SHRINKAGE, ELASTIC SHORTENING, BRAKING FORCES, WIND FORCES, ETC., ACTING ON THE SUPERSTRUCTURE AND THEIR TRANSMISSION TO THE BRIDGE SUPPORTS. /RRL(A)/
