Capita Selecta Concrete Structures

Part A: Temperature effects

Temperature effects in hardening and hardened concrete. Emphasis on difference between structural response under external loads and imposed deformations. Both materials aspects and structural aspects are dealt with. Aspects of building physics are considered briefly (temperature calculations).

A specific topic concerns the behaviour of hardening concrete. Problems with young concrete are discussed from both the scientific and engineering point of view.

Attention is given to judgement of crack patterns and failure causes in hardening and hardened concrete structures.

Effect of imposed deformations on safety and durability at dealt with.

Part B: Silo's, reservoirs, storage and concrete protective structures

Loads and design criteria for storage structures

- Hydrostatic and/or bulk loads

- Tightness criteria

- Load factors

- Design of rectangular and cylindrical reservoirs in reinforced and prestressed concrete.

- Concrete protective structures under extreme loads, e.g. impact, blast, fire, cryogenic loads. Modelling of extreme loads and response of concrete and concrete structures under extreme load conditions is given due attention. General principles of judgement of protective systems and the consequences of this for the design is dealt with.

An obligatory exercise (1 credit point) covers essential aspects from parts A and B. The exercise concerns a reinforced of prestressed reservoir under hydrostatic and thermal load.
