EXPERIMENTAL INVESTIGATIONS ON THE STRUCTURAL BEHAVIOUR OF SEGMENTAL PRECAST PRESTRESSED GIRDERS/ VERSUCHE ZUM TRAGVERHALTEN VON SEGMENTAEREN SPANNBETONTRAEGERN.

A REPORT ON EXPERIMENTAL INVESTIGATIONS TO DETERMINE THE STRUCTURAL BEHAVIOR OF SEGMENTAL PRECAST PRESTRESSED GIRDERS WITH CEMENT MORTAR JOINTS AND EPOXY BONDED JOINTS IS PRESENTED. THE STRUCTURAL BEHAVIOR (CRACKING) AND THE LOAD CAPACITY (ESPECIALLY CONCERNING TRANSVERSE SHEAR) WERE INVESTIGATED BY LOAD TESTS ON TWO PRESTRESSED GIRDERS, ABOUT 9 M LONG AND 70 CM DEEP. THE GIRDER WITH CLOSED JOINTS OF MODIFIED CEMENTMORTAR SHOWED THE SAME FAVORABLE BEHAVIOR AS THE GIRDER WITH EPOXY BONDED CLOSED JOINTS. IN GERMAN WITH ENGLISH ABSTRACT.
