“…In developing countries, it is relatively more likely for concrete masonry units (CMUs), mortar and concrete usually to lack a sufficient amount of cement because of attempts to reduce cost and improve workability by using relatively high water to cement ratios. Low compressive strength levels have been reported ranging between 3 and 10 MPa (considering the net area) for CMUs, 5 to 10 MPa for mortar, and 8 to 12 MPa for concrete (Yamin and Garcia 1994, Tena-Colunga et al 2008, Eberhard et al 2010. The longitudinal reinforcement of tie columns and beams typically consists of #3 (9.5 mm) and #4 (12.7 mm) diameter steel rebars, either deformed or with a smooth surface.…”

Confined masonry (CM) consists of unreinforced masonry walls confined with reinforced concrete tie columns and beams. Due to satisfactory performance during past earthquakes, CM has become the predominant construction style in several developing countries. However, poor construction practices and substandard materials may result in inadequate performance.This paper evaluates the feasibility and efficiency of an affordable and practical retrofit technology designed for CM constructions in developing areas. Corrosion-resistant aluminum strips are inserted into grooves and embedded in mortar along bed joints to enhance the in-plane shear resistance and deformability. Experimental evidence was obtained through in-plane cyclic load tests on full-scale CM walls. It is shown that a substandard CM wall can be transformed into a wall with acceptable strength and deformability, and the in-plane shear strength of a retrofitted wall can be estimated by means of a simple analytical model that accounts for the contribution of the horizontal reinforcement.

“…Chiou [14] investigated the structural behavior of a framed masonry wall subjected to in-plane monotonic loading by a full-scale test and the method of discontinuous deformation analysis. Confined masonry panels were found to provide fair in-plane shear capacity and ductility by Hori [15], Tena-Colunga [16] and Tomazevic [17]. Tasnimi [18] presented an experimental program to investigate the in-plane seismic behavior of steel frames with clay brick masonry infills having openings.…”

Abstract. For in ll panels, the expected strength is very close to the cracking strength; however, experimental values of the cracking strength are very scattered, and there is no formula to estimate it accurately. That is why some new codes have been assumed to focus on determining the expected strengths of In ll panels by their maximum strengths. In this paper, an extensive statistical analysis is conducted on experimental data to achieve a formula for the maximum (mostly referred as ultimate) strength of solid masonry in lled frames. For the ultimate strength, reliability of the existing empirical relations (9 formulas) is investigated, based on the available experimental data, categorized in accordance with their con ning frames. The obtained results of 51 experimental specimens show that the formula, recommended by Maintone et al., is the best one; however, it mostly underestimates the ultimate strength and is more accurate for the in lls in concrete frames. The formula is also improved to have a better correlation with the experimental data.
