| 摘要： | Masonry walls and columns are common structural members that typically resist compressive loads, with a number of such members being required to resist combined axial load and out-of-plane bending due to direct out-of-plane loads or an eccentricity of the axial compressive load. Flexural compression strength is usually greater than axial compression strength, and a reasonable experimental data set supports this assertion. However, little information exists for high-strength concrete block masonry subjected to combined axial and flexural loadings. This paper presents axial and flexural compression strengths and deformation properties of high-strength concrete block masonry. Seventy-two masonry prisms were constructed and tested to evaluate the capacity and behavior of high-strength structural masonry subject to compressive concentric and eccentric loading; both grouted and hollow prisms were used. Block strengths of 44, 56, and 67 MPa are considered. The results show an increase of flexural compression strength of 15-29％ for the hollow prisms and of 70-79％ for the grouted prisms compared with their axial compression strength. Measured ultimate strain varies from 0.14 to 0.19％ for the axial compression and from 0.20 to 0.25％ for the flexural compression. Hollow prism strength varies from 52 to 62％ of the block strength, whereas grouted prism strength varies from 43 to 59％ of the block strength. |
