Procedure for Design of Abutments

A series of steps must be followed to obtain a satisfactory design.STEP 1: SELECT PRELIMINARY PROPORTIONS OF THE WALL.STEP 2: DETERMINE LOADS AND EARTH PRESSURES.STEP 3: CALCULATE MAGNITUDE OF REACTION FORCES ON BASE.STEP 4: CHECK STABILITY AND SAFETY CRITERIAa. Location of normal component of reactions.b. Adequacy of bearing pressure.c. Safety…continue reading →

What is influence line Diagram? difference between bending moment diagram and influence line diagram

Concept of Influence line was developed by Winkler in 1867. Influence Diagram concept is used for analysis of structures that are subjected to variable or moving loads. Structures like bridges, culverts and even roofs of a house is also such structures that have live and moving loads.DefinitionInfluence line is defined…continue reading →

Download Structural Steel Designer\’s Handbook by Roger and Frederick Free [PDF]

Steel structures are considered highly effective in terms of light weight and high rise structures. They are more earth quake resistant and more long lasting. Steel structures needs more maintenance and care as compared with concrete structures.In advanced countries steel structures are preferred as compared to concrete structures. The availability…continue reading →

Design of Flat Plate Slab [pdf]

Structural Concrete Slabs are constructed to provide flat surfaces, usually horizontal, in building floors, roofs, bridges, and other types of structures. The slab may be supported by walls, by reinforced concrete beams usually cast monolithically with the slab, by structural steel beams, by columns, or by the ground. The depth…continue reading →
