Some days ago I have posted a Picture of an eccentric isolated foundation and I asked my fans on facebook that whether it is right to place an isolated column foundation like this or not? As a result I have ...

To determine the orientation of guided bearings, one should understand the movement of curved region of a prestressed bridge. Movement of prestress and creep are tangential to the curvature of the bridge (or along longitudinal axis) while the movement due ...

Basically, piers constructed monolithically with the bridge deck are advantageous in the following ways: (i) Movement of the bridge deck is achieved by the bending deformation of long and slender piers. In this way, it saves the construction cost of ...

Diaphragms are adopted in concrete box girder bridges to transfer loads from bridge decks to bearings. Since the depth of diaphragms normally exceeds the width by two times, they are usually designed as deep beams. However, diaphragms may not be ...

In roller bearing for a given movement the roller bearing exhibit a change in pressure centre from its original position by one-half of its movement based on David J. Lee.  However, with sliding bearing a sliding plate is attached to ...

From aesthetic point of view, an odd number of spans with a decrease in length in the direction of abutment is desirable. Moreover, spans of equal length are found to be boring. However, the arrangement of irregular span lengths is ...

In the conventional design of steel reinforcement for a simply supported skew bridge, a set of reinforcement is usually placed parallel to free edge while the other set is designed parallel to the fixed edge. However, this kind of arrangement ...

We all know that concrete is vulnerable to temperature changes it usually shrinks and expands due to some temperature variations, in such a condition most of the times a crack is intentionally introduced so that any expansion or shrinkage in ...

Prestressing is now a must-to-have phenomenon in every mega project whether it includes flyovers or dam or whatever. During the design procedures a very important question that arises in the mind of the engineer is; whether to use jacking at ...

Dampness is the cause, reason and initiator of many defects and diseases in all sorts of construction from roads and transport systems to building and housing facilities. It might be a headache for you in rainy season and it might ...
