ECC Beam Shear Test Set 11 - 2 #7 rebar, 33

The purpose of this test was to determine the shear capacity, shear stiffness and failure mode of a series of ECC beam specimens with a 1000/B factor (Refer to ACI-ASCE document 426: "Shear and diagonal Tension") of around 0.087 [psi]. Two simply-supported ECC beam specimens without transverse reinforcement in the shear span were tested under point loading arranged in an assymetrical pattern. Shear failure was forced to occur at one end of the specimen. Specimens were constructed using mild steel longitudinal reinforcement and Strain Hardening PVA-Engineered Cementitious Composite (ECC) material. Other material properties and important specimen properties are given next.

b=5.0 in., h= 12 in., As=2#7 (1.20 in2), d=10.1 in., a/d= 3.3, f'ecc=7.0 ksi. No transverse reinforcement in the shear span. Web reinforcement outside the shear span consisted in #3 closed stirrups (2 legs) spaced at 2.0" on centers.

Test data is organized as follows:
Beams A and B were constructed the same way (materials, reinforcement, etc.), but are two different specimens. In comparison to other test sets, these beams were NOT repaired and retested. Data for each beam test (A and B) is stored as separate repetitions.
