CLIENT: Pedelta

LOCATION: Barcelona (Spain)

KEY ELEMENTS: Composite materials, GFRP, pultruded profiles

SERVICES: RESEARCH AND DEVELOPMENT

BUDGET: US$ 13,500

PROJECT DURATION: Design 2008

PEDELTA’S KEY PERSONNEL: Juan Sobrino, PhD, PEng, PE; Javier Jordán, MSc, PE

PROJECT DESCRIPTION

Several laboratory test were performed at the Institute of Building Sciences Eduardo Torroja (IETcc) in order to test the strength capacity of pultruded profiles in composites material reinforced with glass fibers, used in the first of our hybrid footbridges steel and GFRP built in Zumaia. The test model was designed for Pedelta by simulating the final status of the profiles. All modes of collapse of the specimen were contrasted very satisfactorily by a finite element simulation performed with sophisticate calculation programs considering the orthotropy of the material.

Some gauges were positioned in order to compare stresses with the traction and shear tests and for measuring horizontal displacements during compression test. The result of this work has allowed an optimization of the joints of the fiberplastic elements with the metallic structure.

Services provided by PEDELTA: Preparation for test and contrast simulation.
