66914 - STRUCTURAL STRENGTHENING AND REHABILITATION

Conoscenze e abilità da conseguire

In the course, the student will know the techniques for the strengthening and rehabilitation of civil structures (buildings and infrastructures), made of reinforced concrete, steel or masonry. The techniques for strengthening in seismic areas will be also studied.

Contenuti

The course topics are listed below:

Analysis of masonry historical and monumental buildings:

• Mechanical properties of masonry constituents: bricks, stones, mortar, natural materials,
• Mechanics of masonry composite materials: compressive, tensile and shear strength,
• Analysis of masonry elements as no tension materials,
• The masonry pier, the lintel beam, the masonry wall,
• Analytical methods for the calculation of the masonry structure,
• Limit analysis method for the out of plane overturning of the masonry wall,
• Numerical analysis of masonry structures: construction of pushover curves,
• Numerical models: plate elements, frame elements and reticular analogy,
• Vaulted structures: groin, barrel and dome vaults,
• Timber beams and timber frames for floors and roofs,
• NDT investigation of masonry and timber materials,
• Examples of damaged buildings of L’Aquila city.

Use of innovative composite materials for special structural problems:

• Fiber reinforced composite materials (FRP),
• Repair and strengthening of R/C structures with FRP,
• Repair and seismic enhancement of timber and masonry structures,
• Innovative constructions with advanced polymer composites,
• Examples of damaged masonry buildings repair and strengthening.

  Fire Engineering:

• The fire event: causes, evolution and thermo – mechanical effects,
• Effect of high temperature on steel, concrete and timber,
• Design of steel structures with passive fire resistance,
• Theromechanical damage of concrete,
• NDT investigation of damaged concrete,
• Repair of fire damaged concrete structures,
• Examples of industrial buildings repair case histories.

  Structural Health Monitoring:
