Foundation Foundation is the part of structure below plinth level up to the soil. It is in direct contact of soil and transmits load of super structure to soil. Generally it is below the ground level. If some part of foundation is above ground level, it is also covered with earth filling. This portion of(…)

SAFE DESIGN AND CONSTRUCTION OF MULTISTOREY RCC BUILDINGS
MULTISTOREY REINFORCED CONCRETE BUILDINGS DESIGN A large number of reinforced concrete multistoreyed frame buildings were heavily damaged and many of them collapsed completely in Bhuj earthquake of 2001 in the towns of Kachchh District (viz., Bhuj, Bhachao, Anjar, Gandhidham and Rapar) and other district towns including Surat and Ahmedabad. In Ahmedabad alone situated at more(…)
DESIGN AND DETAILING OF RCC BEAMS
RCC beams structural elements are designed to carry transverse external loads that cause bending moment, shear forces and in some cases torsion across their length. Concrete is strong in compression and very weak in tension. Steel reinforcement is used to take up tensile stresses in reinforced concrete beams. Mild steel bars of round section were(…)
TYPES AND DESIGN OF STEEL CHIMNEY
The design of steel chimney can be done as two types: Self-supporting steel chimneys Guyed steel chimneys. Self-supporting steel chimneys: When the lateral forces (wind or seismic forces) are transmitted to the foundation by the cantilever action of the chimney, then the chimney is known as self-supporting chimney. The self-supporting chimney together with the(…)
Portal Frame Design With Example
Portal Frame Design with Example Design Steps: 1. Design of slabs 2. Preliminary design of beams and columns 3. Analysis 4. Design of beams 5. Design of Columns 6. Design of footings Problem: A portal frame hinged at base has following data: Spacing of portal frames = 4m Height of columns = 4m Distance between(…)
BLAST RESISTANT DESIGN OF STRUCTURES
Reinforced concrete can provide substantial protection from even extreme blast loading. The relatively large mass of concrete elements provides an inherent resistance to impulsive loads. Structural design considerations include sizing members to provide an expected degree of deformation and associated damage and optimizing the structure to resist and transfer blast loads in a reliable manner.(…)
Concept of Reinforced Earth Structures Design
Reinforced earth is a composite material formed by the friction between the earth and the reinforcement. By means of friction the soil transfers to the reinforcement the forces built up in the earth mass. The reinforcement thus develops tension and the earth behaves as if it has cohesion. COMPONENTS OF REINFORCED EARTH SOIL SKIN REINFORCEMENT(…)
Roof Truss Design
Selection of Roof Trusses Architectural style, types of roofing material, methods of support of column framing, and relative economy are the principal factors influencing a choice among the three basic types of trusses: bowstring, pitched, and flat. In addition, side- and end-wall height and type, roof shape, and bracing requirements must be considered. Other factors(…)
