The building brick game chosen for analysis was the Arckit, since it is suitable for the architectural practice. It is estimated that this game can contribute to the design, representation and presentation of projects. In order to investigate in which aspects Arckit presents possibilities of applications, as well as limitations of use, the article approaches the importance of building bricks as a didactic tool and its use in the field of the architectural design process. From a literature review and an empirical experience, this article reports a qualitative research, where the applicability of the Arckit game was checked. Through a critical reflection based on that experience, it was possible to conclude that whereas its limitations to urban form and linked to the formal vocabulary that composes the grammar of these bricks, the Arckit building bricks represent in architecture a playful and experimental way to think and design, fomenting the creativity and the spatial perception, resulting in a particular experience that can make architecture better connected with dreams and joy.展开更多

To better understand the damage of brick masonry buildings under the impact of boulders, a "block-joint" model is developed using threedimensional discontinuous deformation analysis(3-D DDA) to simulate the behaviour of the "brick-mortar" structure. The "block-joint" model is used to capture not only the large displacement and deformation of individual bricks but also the large-scale sliding and opening along the mortar between the bricks. The linear elastic constitutive model is applied to account for the non-plastic deformation behaviour of brick materials. Furthermore, the mechanical characteristics of the mortar are represented using the Mohr-Coulomb and Drucker-Prager criteria. To propose safe structural design schemes and effective reinforcement for brick masonry buildings, seven construction techniques are considered, includingdifferent grades of brick and mortar, effective shear areas and reinforced members. The proposed 3-D DDA model is used to analyse the velocity distribution and the key point displacements of the brick masonry building under the impact of boulders. The results show that upgrading the brick and mortar, increasing the wall thickness, making full use of the wall thickness, and adding a circular beam and structural column are very effective approaches for improving the impact resistance of brick masonry buildings.展开更多

The experimental results indicate that, after carbonation, the strength of the brick increases, its drying shrinkage reduces, and its soundness becomes eligible. The optimal slaked lime/steel slag（SL/SS） ratio for the carbonated brick is 0.2 and the asprepared brick meets the requirements of the Chinese standard for MU20-grade building bricks, additionally, it also demonstrates prominent environmental benefits. The XRD and pore structure analyses indicate that the excellent properties of this carbonated brick are attributed to the formation of carbonate crystals and the dense structure due to the carbonation.展开更多
