Clinging to existing buildings

Overview of technical solutions

The intensity of loads transmitted between old and new buildings often requires high performance and reliable technical solutions.

Widely used in the past, anchor bolts and carp bolts are possible attachment solutions for shear-only connections. The use of these devices is tricky for parts subject to pull-out forces when they are part of a construction's stability system. In such cases, conventional systems such as crosshead or hammerhead anchors need to be adapted.

The use of mechanical and chemical anchors has become very common. Figure 6 shows the three generic types of heavy-duty anchor and their indicative performance levels. The main...
