High Stiffness Flexural Frame, 200 kN Cap., DUPLEX

Model：DUPLEX

Use：This high stiffness flexural frame has been designed to have a double testing mode: parallel and orthogonal.

Standard：EN 14488-5, EN 14651,EN 12390-5 ,ASTM C293 ,ASTM C78 ,EN 1339 ,EN 1340 ,ASTM C1609

Description

This high stiffness flexural frame has been designed to have a double testing mode: parallel and orthogonal.

Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e.g. fiber reinforced concrete (FRC) and sprayed concrete.
These tests are significantly affected by the actual frame stiffness therefore the relevant international Standards state stiffness limits which are exceeded by this new model (better than 200 kN/mm).
This remarkable result comes from the frame sections but it is also derived from the particular layout which keeps the specimen aligned with the frame crossbeams maximizing structural rigidity.

Orthogonal mode is meant to be used to test long specimens having more than 650mm length.

The horizontal daylight accommodates large specimens (slab, flagstones), concrete beams and kerbs long up to 650 mm.

Two models are available, either with pressure transducer or with load cell, both fitted with piston travel limit switch and connection kit to separate control console.
 
Frames are available with either pressure transducer or load cell (recommended for FRC testing) and are fitted with piston travel limit switch and connection kit to the control console. Bearers not included. See accessories.
