Abstract
The compressive performance of grouted mortarless masonry prisms strengthened with glass fiber-reinforced polymer (GFRP) composites was investigated in this study. A total of 18 grouted mortarless masonry specimens, i.e., nine strengthened with GFRP (called G-GMM) and nine without GFRP (called GMM), were tested under uniaxial compression. The effect of grout strength on the compressive strength of the prisms was discussed. Moreover, the effect of GFRP on the cracking load, modulus of elasticity, ultimate bearing capacity, failure modes, compressive stress–strain behavior, and deformation behavior of the specimens was analyzed. The test results indicated that GFRP strengthening increased the ratio of initial cracking load and ultimate load bearing capacity of mortarless masonry to a great extent, i.e., the ratio is 50–80% for G-GMM and 40–65% for GMM. In addition, GFRP clearly improved the deformation capability of the GMM. The tested experimental data were in good agreement with the predicted values using classic expressions.
Highlights
Masonry has been widely used in structural application due to its typical compressive strength.The compressive strength of masonry is one of the critical characteristics of designing masonry structure, and it depends on several parameters such as mortar strength, grouting, grout strength, and bond pattern [1,2]
The compressive parameters, i.e., the initial cracking load, ultimate load, ultimate stress, failure modes of the specimens obtained from the test are provided in Table 4, and the tested results were compared with the standard calculated values
This study investigated the compressive behavior of grouted mortarless masonry reinforced with
Summary
Masonry has been widely used in structural application due to its typical compressive strength. Grout did restrict the initial deformation of mortarless masonry, and improved its ultimate load capacity to a great extent [6,7], and compared the compressive behavior of grouted mortarless masonry and the ungrouted mortarless prisms. Fiber Reinforced Polymers (FRP) have been widely researched and used in strengthening and retrofitting engineering structures to increase the carrying capacity or ductility because of their significant characteristics such as high strength and increased deformation capability [10,11,12,13], and there are lots of functional analytical models for better understanding and explanation for FRP confinement [14,15]. The experimental results presented in this study will be used as the references for the following studies on large-scale grouted mortarless masonry columns
