of nonlinear deformations to zones where repair can be done more economically and without disturbance to building function. A study was done (Abrams, et al. 2015) to demonstrate this concept where reinforced masonry structural panels were attached to a structural steel gravity-designed frame with steel connector plates (Figure 2). This system was termed "hybrid masonry" since the masonry and steel frame act as a composite system.

Most researchers (Li et al., 2015; Okail et al., 2016; Yoshimura et al., 2004b) by investigating the effect of tensile reinforcement ratio of column ties on the seismic behaviour of confined masonry walls, concluded that by increasing the reinforcement ratio of column ties, the seismic performance of confined masonry walls is additionally enhanced. While Yoshimura et al. (2004b) and Li et al. (2015) investigated with longitudinal reinforcements, Okail et al. (2016) investigated on both longitudinal and transverse reinforcements. However, when the effect of reinforcement ratio was investigated on confined masonry walls using handmade bricks of low compressive strength, Quiroz et al. (2014) observed that the increase in the reinforcement percentage of the column tie did not improve the seismic performance of confined masonry walls. This skewed result needs further confirmation through research on confined masonry walls using low compressive strength bricks. Li et al. (2015), on the other hand, defined a new type of masonry construction “Hybrid Masonry – Reinforced Concrete Structure” (HMRCS), by increasing the sizes and reinforcement ratios of the confining elements. By doing so, the confining elements would not only act as confinement in a confined masonry structure but also assist in resisting gravity and lateral loads. However, a line of demarcation between confined masonry, HMRCS and reinforced concrete frame has to be drawn in terms of reinforcement ratios and sizes of confining beams and columns.
