What Is An Automatic Level?

What Is An Automatic Level? A dumpy level, builder's auto level, leveling instrument, or automatic level is an optical instrument used to establish or verify points in the same horizontal plane. It is used in surveying and building with a vertical staff...

How to determine the size of elastomeric bearings?

How to determine the size of elastomeric bearings?  For elastomeric bearing, the vertical load is resisted by its compression while shear resistance of the bearing controls the horizontal movements. The design of elastomeric bearings are based on striking a balance between the...

What are the advantages of assigning the central pier and the abutment as fixed piers?

Why should pumping be not used in case of concreting works?

Why should pumping be not used in case of concreting works?During the pumping operation the pump exerted pressure must overcome any friction between the pumping pipes and the concrete, also the weight of the concrete and the pressure head when the concrete...

What reinforcements are used in the process of prestressing?

What reinforcements are used in the process of prestressing?The major types of reinforcements used in prestressing are:> Spalling Reinforcement: The spalling stresses leads to stress behind the loaded area of the anchor blocks. This results in the breaking off of the surface...

Why are steel plates inserted inside bearings in elastomeric bearings?

Why are steel plates inserted inside bearings in elastomeric bearings?In order to make a elastomeric bearing act/ function as a soft spring it should be made to allow it to bulge laterally and also the stiffness compression can be increased by simply...

What do you understand by “preset” during the installation process of bridge bearings?

What do you understand by “preset” during the installation process of bridge bearings?During the installation of bridge bearings the size of the upper plates is reduced to save the material costs. This process is known as preset. Generally the upper bearing plate...
