Effect of Mortar Type on the Seismic Response of Partially Grouted Reinforced Masonry Shear Walls
Since the establishment of ASTM standard C91, masonry cement mortars have become widely used for masonry construction in low to moderate seismic regions. However, the Masonry Standards Joint Committee Code prohibits the use of masonry cement mortars in lateral force resisting systems for structures that fall into Seismic Design Categories D, E, and F. The general objective of this study is to e...
متن کاملStability of ancient masonry towers: Moisture diffusion, carbonation and size effect
Moisture diffusion and carbonation influence the behavior of multiple-leaf ancient masonry walls, producing during centuries a redistribution of stresses from the core of lime mortar concrete to the external cladding of stiff masonry. This is likely one of the causes of long-time damage of some ancient masonry towers. With these motivations, coupled processes of moisture diffusion, carbon dioxi...
متن کاملStability of ancient masonry towers: Stress redistribution due to drying, carbonation, and creep
Extending the analysis of the evolution of pore humidity and carbonation presented in a preceding paper by Ferretti and Baz ̆ant, this paper analyzes the redistribution in time of vertical normal stresses across the multiple-leaf wall of ancient towers, using the example of collapsed Pavia Tower. It is shown that stress redistribution due to nonuniform shrinkage and nonuniform creep across the w...
متن کاملThe taste of carbonation.
Carbonated beverages are commonly available and immensely popular, but little is known about the cellular and molecular mechanisms underlying the perception of carbonation in the mouth. In mammals, carbonation elicits both somatosensory and chemosensory responses, including activation of taste neurons. We have identified the cellular and molecular substrates for the taste of carbonation. By tar...
متن کاملExperimental study of grouted sleeve lapping connector under tensile load
The performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for ...
