Performance of unreinforced masonry strengthened with bed joint reinforced repointing

Bed joint reinforced repointing is a strengthening method often used in the Netherlands to counteract settlement damage. This strengthening technique consists of cutting a slot in the mortar joint and installing twisted steel bars embedded in a high-strength repair mortar. Due to the increase in seismic activities, triggered by gas extraction in...

Experimental and numerical study of historic masonry with bed joint reinforced repointing

Induced seismicity due to gas extraction in the province of Groningen in the Netherlands has a noticeable impact on building structures. Historic masonry structures in the area, which are non-engineered and lacking empirical design features often present in traditionally seismic regions, are especially vulnerable to dynamic loading. Compounding...

In-plane seismic behaviour of retrofitted masonry walls subjected to subsidence-induced damage

The province of Groningen in the Netherlands is experiencing the continuous impact of gas extraction in the form of induced seismicity. Due to the absence of naturally occurring seismicity in the region, the historic building stock of Groningen was constructed without empirical design features typically encountered in naturally seismic...
