What are the sources of weakness in RC frame building?
Damages appearing in the buildings may occur due to several reasons such as site effect, poor construction quality, poor concrete strength, poor detailing in beam-column joints, detailing of stronger beam than column, soft stories, weak stories, inadequate reinforcement, short lap splices, incorrect end hook angle, and …
Why should masonry buildings have simple structural configuration?
Why should Masonry Buildings have simple Structural Configuration? Brick masonry buildings have large mass and hence attract large horizontal forces during earthquake shaking. The focus of earthquake resistant masonry building construction is to ensure that these effects are sustained without major damage or collapse.
What is the RCC structure?
R.C.C. Structure design :a combination of concrete and steel reinforcement that are joined into one piece and work together in a structure. The term “reinforced concrete” is frequently used as a collective name for reinforced-concrete structural members and products.
What is the problem of rehabilitation *?
Explanation: The problem of rehabilitation is Unique, For the particular structure and hence the use of common techniques for rehabilitation of various structures is limited and as far as maintenance is concerned, several new cementations materials and epoxy resigns and compounds have been developed which are highly …
What types of faults cause earthquakes?
Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
What are the most important earthquake resistant features in masonry building?
Horizontal bands are the most important earthquake-resistant feature in masonry buildings.
Why is vertical reinforcement required in masonry buildings?
Adequate cross-sectional area of these vertical bars prevents the bar from yielding in tension. Further, the vertical bars also help protect the wall from sliding as well as from collapsing in the weak direction. Sliding failure mentioned above is rare, even in unconfined masonry buildings.
What is a load bearing element?
Load Bearing Elements (LBE), also known as Barrettes, is a term that refers to the use of single or multiple arrangements of rectangular elements to support significant structural loads for structures.
What is the effect of efflorescence on building?
Effects of Efflorescence: Effects of efflorescence is damp wall leading to various damages like unhygienic conditions, decay, dry rot of woodwork, disintegration of masonry, damage to furniture and internal decorations, crumbling of plaster, etc.
