Masonry arching action

WebArching or compressive membrane action (CMA) in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete. … WebHowever, walls confined between rigid supports can display very high resistance to out-of-plane forces through the development of arching action in flexure. Therefore it is recommended, in order to achieve an optimal load-bearing behavior, or rather stability, that the remaining gap at the top of a wall is filled with nonshrinkable mortar some days after …

Discussion of “Arching Action Theory of Masonry Walls”

Webtechniques have been used for masonry wall systems that involve either (1) adding mass to the wall system by increasing its wall thickness by using a back-up wall system WebProposed theory to explain and predict relatively great strength of masonry walls constrained between essentially rigid supports; comparison with available test data on lateral loading of brick beams; theory used to obtain static load deflection curves for masonry beams of solid cross section; results compare reasonably well with test data ...
