Abstract:

Test results of six full-scale reinforced concrete flat plate edge connections with an opening in the vicinity of the column are reported. The test specimens represent a portion of a slab bounded by the lines of contraflexure around the column. The tests were designed to study the effect of openings on the punching shear behavior of the slab-column edge connections. The test parameters were the location and the size of the openings. One specimen had no opening and the remaining five had various arrangements of openings around the column. All specimens were cast with normal density concrete of approximately 32 MPa compressive strength. The openings in the specimens were square, with the sides parallel to the sides of the column. Two sizes of openings were used: the same size as the column (250 x 250 mm), and 60 percent of the column size (150 x 150 mm). The design procedures in the American and Canadian Codes (ACI 318M- 95 and CSA A23.3-M94) are discussed and compared with the test results.

Abstract:

A rational approach for calculating the serviceability structural effects of creep on reinforced concrete columns and beams is proposed. The approach uses creep properties as input, exemplified by the creep coefficient, and produces deflections of members and stresses in concrete and steel as output. The approach defines an effective modulus of elasticity for the reinforced section and uses a trial-and-error approach for its solution. The application of the method is made simple by the use of a microcomputer. The results of a specific example, solved by means of this approach and compared with procedures given in the ACI Building Code (318M-83) and British Standards Institution Standard BS 8110, point toward good correlation and, considering the degree of uncertainty associated with the problem, confirm that the method is reasonably accurate.
