“…Some experimental investigations had focused on the static in-plane and out-of-plane behavior of the brick masonry veneer systems [10,12,13,19,20]. Some of the works have also focused on the dynamic shaking table tests of both brick veneer elements [7,10,12,13,16,[21][22][23][24] or full-scale or reduced-scale buildings with attached brick veneer walls [10,12,19,21,[25][26][27][28][29].…”

Brick masonry veneer walls connected to infill walls inserted in a reinforced concrete (RC) frame are a common constructive system in Portugal. The stability of the veneer wall is ensured by ties that make the connection with the masonry infill walls. These ties enable the transferring of out-of-plane loads to the main structure due to wind, and particularly due to earthquakes. However, the characterization of the seismic behavior of these tie connections is an insufficiently explored topic. The present paper shows a numerical investigation that aims to simulate experimental results of tension and compression tests performed on masonry prisms connected by means of steel ties. The main objective of the present research is to obtain a better understanding of the complex structural behavior of this specific construction system to then develop simplified numerical tools to be used in engineering practice for the seismic design and retrofitting of brick masonry veneer walls. The numerical results match well the experimental ones, and the validated approach can be used in the future to carry out parametric analyses to evaluate the influence of material and geometric properties of the tie and masonry, as well as the type of action and construction details.

“…Kasal et al [13] performed a series of dynamic experiments on two-story glue-laminated timber frames with fiber-reinforced joints to obtain connection characteristics. Okail et al [14] presented the findings of shakingtable experiments conducted to examine the seismic performance of a full-scale, one-story, wood-framed structure with masonry veneer. e full-scale timber frame walls were tested to study their performance under compression and the results indicated that the stud-to-stud connections offered better improvement of load carrying capacity for the specimens under compression [15].…”

To prevent the wooden door frame of traditional rural houses from being stuck due to diamond deformation under earthquake and improve the seismic capacity of rural houses, an innovative method of reinforcing the angular displacement of the wooden door frame with channel steel and the diagonal brace is proposed. The rationality of the finite element simulation is demonstrated by comparing the results of finite element simulation and quasistatic test based on reinforced and unreinforced wooden door frame specimens. On the basis of the finite element model of wooden door frame, the seismic performance of channel type and diagonal brace thickness of reinforced wooden door frame and the seismic performance of friction coefficient of unreinforced wooden door frame are studied, respectively. The results show that the lateral stiffness and the lateral bearing capacity of the reinforced wooden door frame increase with the increase of channel steel type and the diagonal brace thickness. The height of the channel steel section of the seismic reinforcement structure should be half of the unreinforced structure. With the increase of the friction coefficient, the lateral bearing capacity of the unreinforced wooden frame increases, while the ductility of the unreinforced wooden frame decreases.

“…The use of clay brick masonry as an anchored wall veneer was first seen in late eighteenth century England (Mendygral and Sumnicht 2011), and today makes up approximately 45% of new residential dwellings in New Zealand (Beattie and Thurston 2011). Clay brick, or similar masonry veneer systems, is favored for its durability and resistance to fire and moisture, as well as for aesthetic reasons (Okail et al 2011). However, observations made from previous earthquakes have highlighted that masonry veneer systems exhibit poor performance when subjected to lateral loads.…”

“…Inadequate performance of masonry veneer systems was observed in the M5.6 1989 Newcastle, Australia earthquake, with pull-out of the ties connecting the veneer to the timber wall framing commonly observed (Page 1991). The M6.7 1994 Northridge, California earthquake also resulted in considerable damage to older brick veneer systems, largely attributed to a combination of differential movement between the masonry veneer and the timber framing and the poor anchorage of ties connecting the masonry veneer to the timber wall framing (Okail et al 2011).…”

“…The earthquake performance of masonry veneer systems attached to lightweight timber framing has been experimentally investigated in both New Zealand and the United States (Thurston and Beattie 2008a, Thurston and Beattie 2008b, Thurston and Beattie 2008c, Thurston and Beattie 2009, Okail et al 2011). Experimental testing of timber-framed walls with masonry veneer was conducted using both quasi-static and dynamic application of lateral forces on one- and two-story systems using various masonry veneer unit and veneer tie types.…”

Observed Performance of Residential Masonry Veneer Construction in the 2010/2011 Canterbury Earthquake Sequence

Following the 2010/2011 Canterbury, New Zealand earthquakes, a detailed door-to-door survey was conducted in the Christchurch region to establish the earthquake performance of lightweight timber-framed residential dwellings with a masonry veneer external cladding system. The post-earthquake survey involved documenting the condition of dwellings in areas that had experienced different levels of earthquake shaking, allowing comparison between the performance of different veneer systems and different shaking intensities. In total, just fewer than 1,100 residential dwellings were inspected throughout the wider Christchurch area. The survey included parameters such as level of veneer damage, type of veneer damage, observed crack widths, and level of repair required. It is concluded that based on observed earthquake performance at the shaking intensities matching or exceeding ultimate limit state loading, the post-1996 veneer fixing details performed satisfactorily and continued use of the detail is recommended without further modification.
