This dataset consists of tests on one-way slabs and walls to study the minimum amount of high-strength steel reinforcement in concrete elements.
Data for the tests on walls is publicly available as of 1/11/2017.
Data for the tests on slabs was updated on 01/08/2017
The tests were conducted at Bowen Laboratory for Large-Scale Civil Engineering Research, Purdue University.
Tests of Reinforced Concrete Slabs
Nine reinforced concrete one-way slabs were tested. All specimens were 8 in. thick and 14 ft. in length. The width of the specimens was either 30 in. or 40 in. depending on the target reinforcement ratio. The gross reinforcement ratio varied between 0.07% and 0.18%. Two grades of longitudinal reinforcing steel were used (Gr. 60 and Gr.120). No transverse reinforcement was used. The specimens were cast in two batches. Concrete strength on test day varied between 7500 and 9000 psi.
The specimens were simply supported at a span of 12 ft. Two different types of loading conditions were used: 1) four-point bending and 2) three-point bending.
Tests of Reinforced Concrete Walls
Four reinforced concrete walls were tested. All specimens were 8 in. thick and 40 in. long in cross-section. The total height of each specimen was 14 ft. The gross distributed reinforcement ratio varied between 0.07% and 0.25%. Two grades of longitudinal reinforcing steel were used (Gr. 60 and Gr.120). No transverse reinforcement was used.
The walls were tested horizontally and spanned 12ft. between simple supports. Load was applied at mid-point resulting in an aspect ratio (height/length) of 1.8.
For all tests included in this dataset:
Applied load was measured using load cells. Displacement along the test span was measured using linear variable differential transformers (LVDT). Optotrak, an optical tracking system was used to track surface deformations.
