In many problems, it is essential to isolate the body under consideration from the other bodies in contact and draw all the forces acting on the body. For this, first the body is drawn and then applied forces, selfweight and the reactions at the points of contact with other bodies are drawn. Such a diagram…
The history and design aspects of the Eiffel Tower are interesting for engineers even today. Wrought iron was used for the construction of Eiffel Tower with the employment of scaffolds. Mathematical formulas were deliberated for numerous calculations for wind forces and load conditions. History Of Eiffel Tower The Eiffel Tower was constructed in Paris for the World…
Sources: The waste generated by agriculture includes waste from crops and live stock. In developing countries, this waste does not pose a serious problem as most of it is used e.g. dung is used for manure, straw is used as fodder. Some agro-based industries produce waste e.g., rice milling, production of tea, tobacco etc. Agricultural wastes…
The combined effects of population explosion and changing modern living standards have had a cumulative effect in the generation of a large amount of various types of wastes. Solid waste can be classified into different types depending on their source. · Municipal solid waste (MSW) · Industrial waste · Hazardous waste · Biomedical or hospital waste: as infectious waste….
Unwelcome sound transmission in a building is typically perceived as a noise problem by the occupants. With more and more people living closer together, soundproof construction techniques are increasingly utilized in reducing noise and providing quieter working and living environments. The Fundamentals of Noise As human population density continually increases, the desire for peaceful, noise…
Composite masonry is the one that is constructed out of two or more types of building units or of different types of building materials. Composite Masonry: When walls are constructed with two or more types of building materials it is term as composite masonry. It makes the used of locally available materials to obtain optimum economy. The composite masonry…
Waste material is a by-product of human and industrial activity that has no residual value. Need for Comprehensive construction waste management in every site. Every personnel, from the management to the operational level should work for the goal of construction waste management. Importance of Recycling Reduce the demand for new resources. Cuts down the cost and effort…
Introduction Before a foundation design can be embarked on, the associated soil profile must be well established. The soil profile is compiled from three cornerstones of information: · assessment of the overall site geology · in-situ testing results, particularly continuous tests, such as the CPTU · laboratory classification and testing of recovered soil samples · pore pressure (piezometer) observations…
Base Isolation also protects non-structural elements and instruments by lessening the entire structure’s speed during an earthquake, as opposed to toning alone. There are a diversity of isolation methods and devices available. Types of base isolation systems There are two basic types of isolation systems; one that uses elastomeric bearings and the other uses sliding…
A second method to determine the value of the coefficient of consolidation is to use only the results of a consolidation test for small values of time, and to use the fact that in the beginning of the process its progress is proportional to the square root of time. In this method the measurement data…
