Soil Nailing | Principles | Advantages

Soil-nailing-done-to-protect-the-highway

Soil Nailing Soil nailing is a ground improvement technique which is used to reinforce soil to make it more stable. Soil nailing is used for slopes, excavations, retaining walls etc. to make it more stable. The faces of steep slopes are usually protected by shotcrete and mesh for temporary works and by either cast-in-place concrete … Read more Soil Nailing | Principles | Advantages

Vibro Stone Columns | Ground Improvement

Installation of Vibro Stone Columns by Vibroflot

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 Vibro Stone Columns | Ground Improvement

Loads on the building

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 Loads on Building for Modeling | Structure Load Calculation | Analyze Building | Excel Spreadsheet

Scaffolding | Scaffold Components | Types

Independent scaffolding with safety signs, lights and hazard warning

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 Scaffolding | Scaffold Components | Types

Base Isolation System: Outline on Principles, Types, Advantages & Applications

Base Isolation for a Building

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 Base Isolation System: Outline on Principles, Types, Advantages & Applications
