Vibro Stone Columns To improve the load bearing capacity of in-situ soils and fills, Vibro stone columns are designed and are used. These columns reduce the differential settlements of non-homogeneous and compressible soils which allows the use of shallow footings and thinner base slabs. For the construction of Vibro stone columns, the vibrator is made … Read more
Lap length in Reinforced Concrete Lap length is one of the important term in the reinforcement. This is usually confused with another important term called development length and anchorage length. In this article, the lap lengths of bars is discussed. During the placement of steel in Reinforced concrete structure, if the required length of single … Read more
Types of Dams A dam is a hydraulic structure or assembly that is constructed across a river to form a reservoir on its upstream side for confining water for various purposes like Hydropower, water supply, flood control, navigation, fishing and recreation, irrigation. Dams are constructed depending on the purpose for which they are used. Different … Read more
Calculation of Building Loads The loads on building, may be a residential or any type of structure, are mainly classified into vertical and horizontal loads. The vertical loads are the dead and live load. The horizontal loads are the earthquake and the wind loads. This is the general classification of loads. In this article, some … Read more
Scaffolding Temporary support required to provide a safe and convenient working surface is known as scaffold or scaffolding. There is a limit to the safe working height at which a worker can access the building work from ground level. Scaffolding is used on new-build projects and for work to existing structures, including maintenance and repair work. The temporary structure … Read more
Introduction Monolithic Dome is thin wall reinforced concrete shell structure. The structure provides safe shelter for the people in the area with hurricanes and earthquakes. This technique is an effective alternative to conventional methods. A Monolithic Dome is a structure cast in a one-piece form. A curve rotated about a central axis to form a … Read more

Major components of this Tunnel Boring Machine includes Cutter head, with cutting discs/tools and Muck buckets to carry and dispose excavated muck Power supply Systems Cutter head rotation & thrust Bracing system … Read more
Base Isolation System: An Outline on Principles, Types, Advantages & Applications What is Base isolation? Base isolation is a state-of-the-art method in which the structure (superstructure) is separated from the base (foundation or substructure) by introducing a suspension system between the base and the main structure. In context of seismic design of structures, base … Read more
