Collapse Loads of Nonprestressed R/C Curved Beams
Publisher: American Society of Civil Engineers
Abstract: A general method of collapse load analysis was proposed by the writers in an earlier paper for reinforced concrete indeterminate frames in which the members are subjected to combined bending, torsion, and shear. The ...
Interpretation of Concrete Strength for Nonstandard Specimens
Publisher: American Society of Civil Engineers
Abstract: A total of about 210 cylinders and cubes of five different sizes and aspect ratios made from eleven batches of concrete were tested in direct compression to establish the interrelationships between their strengths. The ...
Punching Shear Strength of Simply Supported Ferrocement Slabs
Publisher: American Society of Civil Engineers
Abstract: The results of punching shear tests on 31 square ferrocement slabs are reported in this paper. The slabs were simply supported on all four sides and tested under a central concentrated load. The parameters investigated ...
Shear Transfer in Reinforced Fiber Concrete
Publisher: American Society of Civil Engineers
Abstract: The shear transfer problem across an initially uncracked plane in reinforced fiber concrete is investigated both analytically and experimentally. The softened truss model for nonfibrous concrete is modified by incorporating ...
Shear Strength of Fibrous Concrete Beams Without Stirrups
Publisher: American Society of Civil Engineers
Abstract: Test data are presented on the shear strength of a series of longitudinally reinforced fibrous concrete beams in which the shear span‐to‐effective depth ratio, volume fraction of fibers, percentage of reinforcement, and ...
Stress-Strain Relationship of High-Strength Concrete in Compression
Publisher: American Society of Civil Engineers
Abstract: An experimental investigation was carried out to generate the complete stress-strain curves of concrete in compression with a strength range of 50–120 MPa. The variation in concrete strength was achieved by varying the ...
Stress-Strain Relationship of Confined High-Strength Plain and Fiber Concrete
Publisher: American Society of Civil Engineers
Abstract: The complete stress-strain curves generated experimentally for high-strength plain and fiber concretes confined by transverse ties are reported in this paper. The test parameters include tie diameter, tie spacing, concrete ...
Stress-Strain Relationship of High-Strength Fiber Concrete in Compression
Publisher: American Society of Civil Engineers
Abstract: Tests conducted to characterize the stress-strain relationship of high-strength fiber concrete in compression using both cylindrical and prismatic specimens are reported. The concrete strength investigated ranges from 70 ...
Correlations between Mechanical Properties of High-Strength Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper discusses some important engineering properties of plain concrete for a wide range of compressive strength. A large volume of selected experimental data has been collected from existing literature and then ...
Shear Transfer across a Crack in Reinforced High-Strength Concrete
Publisher: American Society of Civil Engineers
Abstract: In this study, the shear transfer behavior of reinforced concrete across a crack is investigated both analytically and experimentally by conducting tests on 19 precracked push-off specimens. The major parameters considered ...
