A micromechanical model is proposed for determining the overall linear elastic mechanical properties of simple-texture brick masonry. The model, originally developed for long-fiber composites, relies on the exact solution due to Eshelby and describes brickwork as a mortar matrix with insertions of elliptical cylinder-shaped bricks. Macroscopic elastic constants are derived from the mechanical properties of the constituent materials and phase volume ratios. Conformity of the suggested model to real brickwork behavior has been verified by performing uniaxial compression tests on masonry panels composed of fired bricks and mud mortar. Composite masonry panels of varying phase percentages were then constructed and tested by replacing several of the fired bricks with mud bricks. Comparison of experimental results with theoretical predictions demonstrates that the model is suitable even in the presence of strongly differentiated phases, and is moreover able to predict different behavior as a function of phase concentration. The model fits experimental results more closely than the micromechanical models previously reported in the literature. 相似文献

The introduction of robots and automation technology to construction operations will require considerable efforts to understand the mechanics of the many tasks better as they relate to building structures. To control arms, grippers, nozzles, and other production devices automatically, the mechanics of tools as they interact and work with the different construction materials requires extensive knowledge. One approach to learn about the behavior of all the components of an automated system for construction is to build scaled prototypes that are able to handle the actual material. This paper describes the design of an automated masonry system for prefabricating brick panels. It discusses the conditions that affect the bond strength of the masonry. It then describes the design and development of a Cartesian robot actuator and scaled‐down mortar spreader system built to test the bond strengths and accuracy of robotically placed bricks. The actual fabrication of the partially functional prototype helped the researchers to gain hands‐on familiarity with the many real‐world obstacles in using automation and robotics in construction. However, the learning experience also included an appreciation of the potentials offered by using advanced technologies in construction. 相似文献
