Masonry Flashcards
What is Masonry?
• Masonry consists of stones and mortar • It is a two-component system and includes composite materials similar to reinforced concrete (steel and concrete)
What are the requirements on Masonry?
• Load-bearing function • Bearing of deformation induced by: • Enclosure of space: • Protection against weather • Sound-insulation • Protection against fire
Which are the forces on a wall?
Example of the stress-strain-relationship of mortar, stone and masonry
Multiaxial stress condition in stone and mortar as a result of external compressive stress
Relation between masonry-compressive strength βw and compressive strength of mortar βm
Admissible compressive strength of masonry
Reduction factor for the strength of masonry
k1 - to increase the safety value of pillars and short walls
k2 - to take into account the reduction of the carrying capacity due to buckling
k3 - to take into account the reduction of the carrying capacity due to the rotation of the end supports of the deck
Possible lines of cracking under tension load
Admissible tensile strength of masonry
Admissible shear strength of masonry
What is reinforced Masonry? How can reinforced masonry be build?
it is reinforced with steel in the masonry joints such as in reinforced concrete.
Deformation of masonry
Modulus of elasticity for different masonry
Damage of masonry
