As we know the technology developed, the construction methods also got evolved and new methods got introduced. Lightweight steel is a good replacement in traditional construction materials. Nowadays the lightweight steel widely uses in building construction both high rise and residential. The adoption of steel instead of brick and concrete is mainly because of the […]

Geotechnical investigations are necessary to obtain information about the physical properties of soil earthworks and foundations for proposed structures. Geological Investigations should be conducted for new projects and reviewed for existing structures to determine the general geologic setting of the area at and near the project. This is also done to determine the geologic conditions

Machine foundation is designed so that the dynamic forces of the machine are safely transmitted to the soil through the foundation. The machine foundation should be designed to limit the amplitude displacement and not disturb the people who work near the machine. When the design of machine foundations does not satisfy the acceptable value of

A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and that is enclosed except for the entrance and the exit, commonly at each end. A pipeline is not considered as a tunnel, though some recent tunnels have been using the immersed tube construction techniques rather than making use of the traditional tunnel boring

Smart materials have different properties that can be changed according to the conditions in a controlled way by external factors, such as temperature, light, stress, moisture, electric or magnetic fields, pH or chemical compounds. These are also known as intelligent or responsive materials. Their unique properties make them crucial materials in many fields of engineering.

Solid Waste Management is used to describe the wastes like the solid and semi-solid materials that are discarded by a community. The solid waste generated through various domestic, commercial, constructional and industrial activities. The safe disposal of the solid waste was not a problem until the population is very small but as the population is

A buttress dam is also called as a hollow dam. It is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of supports. A reinforced concrete slab or a series of arches or thickened buttress heads may form the sloping membrane for retaining the
