ECC Beam Shear Test Set 4 - 3 #5 rebar, 16

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 0.216 [psi]. Four simply-supported ECC beam specimens without transverse reinforcement were tested under point loading arranged in an assymetrical pattern. Shear failure was forced to occur at one end of the specimen -typically the one closest to the support-. 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=3#5 (0.93 in2), d=10.9 in., a/d= 1.1, f'ecc=5.1 ksi. No transverse reinforcement.

Test data is organized as follows:
Beams A and B were constructed the same way (materials, reinforcement, etc.), but are two different specimens. These beams were repaired and re-tested and were renamed beams C and D, respectively. Data for each beam test (A, B, C, and D) is stored as separate repetitions.
