Block's SMArchS thesis
at MIT under supervision of Prof. John
presents a new methodology to create structural analysis tools based on limit
state analysis for vaulted masonry buildings.
Thrust lines are used to visualize the forces within the masonry and to predict
possible collapse modes.
The project presents a series of
analytical tools that are fast and easy to use in real time, but at the
same time rigorous and highly accurate. The models are interactive and
parametric to explore relationships between building geometry and possible
equilibrium conditions in real time. Collapse analysis due to applied
displacements is determined by combining kinematics and statics. Find a paper

The website features:
- some examples of interactive applets created using the proposed methodology,
- step-by-step tutorials that shows how to make these models (we recommend to
try it out!), and
- reference to the thesis and other material for more examples of the
possibilities of this approach.
