Introduction
- A multitude of small details in columns, corners or
connections decide whether a building will survive
- r not

Introduction
- Quality control is overwhelmed by this
- requirement. Its like a game of chance, even for
the same type of building in the same location

Introduction
- Therefore, we need new
structural concepts adapted to earthquakes
- Buildings form mechanism
during earthquakes
- So why not introduce
efficient mechanisms up front and control them?

A closer look at Hyde systems
- requires only a simple structural model

A closer look at Hyde systems
- that has been verified with large-scale pseudo-dynamic tests at
JRC-Ispra
- n a !/2-scale steel frame with shear-panels

A closer look at Hyde systems
- and on a full-scale masonry in-filled
rc-frame with friction connections

A closer look at Hyde systems
- This model yields a Hyde
system design based on conventional linear limit states in the seismic link

13
A closer look at Hyde systems
- The comparison with a
conventional structure shows:
- Reduced stresses and
reduced deformations

Conclusions
- Conventional structures cannot be produced with the quality
required for earthquake safety of large numbers of buildings due to a multitude of critical details: Too much can and will go wrong
- Structural control systems are superior in performance,
reliability and price and have become a viable alternative
- Base Isolation, Tendon Systems, Pagoda Systems and Hyde
Systems use passive or semi-active control and may be used in new structures as well as in structural rehab
- The Hyde system is of particular advantage providing a better
performance and price for low to medium high residential or mixed residential-commercial buildings
- The Hyde system is the most economical concept to retrofit soft
storey buildings. Tenant activities are hardly affected.
