Such structures need to be sufficiently strong and as economical as possible. Earth-retaining structures usually consist of masonry walls or continuous concrete walls. It is concluded that this new method of testing is a convenient protocol to evaluate the in-plane performance of masonry walls. The crack failure patterns of unreinforced and reinforced masonry have been compared. Later, the system with RC roof and added mass was tested for lateral dynamic loads using shock table testing facility.

The results of free vibration tests have been validated by finite element analysis. This masonry system was further tested with and without added mass. In this paper, a comparative study of free vibration response of unreinforced and reinforced hollow concrete block masonry with and without reinforced concrete diaphragm has been carried out. Of late, reinforced masonry using engineered blocks, has been considered as a better alternative to conventional unreinforced masonry. The lateral load resistance of masonry may be mainly attributed to the in-plane resistance of walls and therefore the detailed evaluation of in-plane performance of masonry walls thus becomes necessary. In a load-bearing masonry system, these lateral loads are known to be shared both by walls in-plane and out-of-plane, with majority being shared by the former owing to higher stiffness along the direction. Unreinforced masonry buildings in particular are known to be heavy in mass and exhibit brittle behaviour and thus unfavourable in resisting lateral forces generated during earthquakes. The study results confirm that the new innovative block can be used for masonry structures. Moreover, the flexural bond strength of the new block is roughly two times higher than that of the conventional block. The results obtained demonstrated that both types of blocks comply with the requirements prescribed by NSR-10. The similitudes or differences between the two types of blocks and prisms were evaluated using ANOVA tests.
Concrete flume diffuser verification#
The verification includes tests of water absorption and compressive strength of blocks, compressive strength of prisms, and flexural bond strength of standard beams.
Concrete flume diffuser code#
The experimental program was planned to verify whether the new block complies with the minimum values prescribed by the NSR-10 Colombian Code for being used as an unreinforced structural masonry block.
The measured response in the new non-conventional block is compared with a conventional solid block. This paper presents and discusses the results of an experimental study aimed at characterizing the mechanical properties of an innovative and patented concrete masonry solid block with non-conventional geometry.
