Types of joints

Material used to fill joints
Joint fillers
Sealants

Since concrete is a brittle material and is strong in compression. It is weak in tension, so steel is used inside concrete for strengthening and reinforcing the tensile strength of concrete.

When completely surrounded by the hardened concrete mass it forms an integral part of the two materials, known as "Reinforced Concrete"... [Read More]

Stone Masonary
Types of bonds

Dampness

Vibrations caused by earthquakes generate additional loading. Shear stresses develop which cause damage to structural elements. Since masonry, which can be stressed relatively high in compression, is weak in resisting bending and shear, collapse often results. The different failures modes of masonry are: [Read More]

1. Sliding Shear Failure
2. Diagonal Cracks
3. Non-Structural Failure
4. Overturning

It is a frame structure single storey unit & includes areas for various purposes, such as transformer generator space. Ultimate Strength Design (USD) or Load and Resistance Factors Design (LRFD) method is used for structural design of all the components. The concrete used for all structural members should have a minimum 28 days cylinder crushing strength of 3,000 Psi.

Multi Storey Building Construction

Bamboo is one of the oldest building materials. If we see in history, bamboo was used for construction of houses in areas where there was abundance of plants especially in South America, Africa& south East Asia.

Climate and Bamboo growth:

Bamboo usually grows at temperature of 250 °C to 500 °C.The ideal place for growth of bamboo is fully water free area. These trees usually grow on sandy soil and clayey soil. Organic soil hinders the growth of bamboo. Bamboo usually reaches at height 75 ft with circumference of 0.3ft..... [Read More]

Factor of Safety in Building Construction

Definition:

The pulling out of steel bars from concrete is resisted by the gripping action of concrete known as bond and the resulting stress is called bond stress. The resistance offered to slipping of bars is due to three factors:

1. The chemical adhesion between the two materials
2. The friction due to natural roughness of bars
3. The mechanical anchorage of the closely spaced rib-shaped deformation made on the bar surface..... [Read More]

Factor of Safety in buildings or other construction is kept so that to compensate any uncertainty in the design process. The uncertainty could come from anywhere in the design process including calculations, material strengths, environmental conditions, natural phenomenons, duty of the structure and last but not the least quality of materials used.

Though there exist some difference when viewed in technical perspective but factor of safety can also be termed as Margin of safety or even Reserve strength..... [Read More]
