Abstract

Load and plate geometry of the bridge structure have form and nature vary. In the finite element modeling, plate weight and the load are converted to point load at the joint of the element. Research to describe plate failure is always carried out through analysis and testing in the laboratory. The aim of this research is to develop methods of analysis and testing High-Performance Fiber-Reinforced Concrete (HPFRC) plate in accordance with geometry and loading program so that the results of laboratory tests can approach the bending behavior of the actual plate element. Analysis carried out by the 2-D isoparametric finite element method, with the approach of plane strain condition. Variations performed on the supporting type, load pattern and the plate depth. Validation performed on plate specimen in the laboratory with a span length of 600 mm, width 300 mm and thickness vary from 30 mm up to 60 mm. HPFRC compressive strength is 93.045 MPa, and a splitting tensile strength is 6.018 MPa. Test performed with four-point bending pattern at a distance of 1/3 span length. Comparison results of analysis and laboratory test can be concluded that the failure of bending plate HPFRC can be described satisfactorily through finite element analysis.
