This seminar introduces methods for the structural analysis of historical monuments, including masonry, timber, iron, steel, and concrete structures. Short lectures will be followed by discussion sessions, together with weekly readings and a series of smaller assignments. Each student will write a final paper on a topic of their choosing. Final papers may be predominantly historical, with structural analysis to support the main arguments, or predominantly structural, with historical analysis to provide context.

The carbonate reservoir is characterized by the fact that the azimuth of fractures is related with structural axis, the developmental extent of fractures and structural location are close related to dip of structure, low-dipping structural axis has not growth fractures. Otherwise, growth fractures, density of fractures are related thickness of layer, more thickness, then less density of fractures. Intra-fracture of layer is main. Some marlstone and anhydrite barriers exist in the reservoir, and become some non-connected oil-water system.
