About The Book
This is perhaps the only comprehensive book on Design and Analysis of Steel Structures, covering a very wide range of Topics including Timber and Plastic Analysis in a single volume.
- The first two chapters give General idea about requirements of steel buildings, Unit weight of materials used, load analysis, types of Structural members used.
- chapter three and four give details of fastening like riveting, welding, bolting "and pin connections.
- Chapter five gives friction grip bolt design. High tensile friction grip bolt are used in all the structures of 60 metres or more in height. They are used in all connections of supports of running machinery or of other live loads which produce impact or reversal of stress.
- Chapter six to eleven deals with design of various structural Components like beams, crane girder, plate girder, tension members, compression members, columns Bases and foundations.
- Chapter twelve and thirteen deals with design of roof trusses, design of portal trusses and workshop buildings.
- Chapter fourteen to eighteen deals with design of Water tanks, self supporting steel stacks or chimneys, shallow bunkers with hopper bottoms, steel bridges, 1 bearings.
- Chapter nineteen deals with Plastic analysis of structures. It' is economical to design the structures based on ultimate Strength and hence behaviour of structures beyond elastic limit is necessary.
- Chapter twenty to twenty-two deals with towers and masts and composite sections.
- Chapter twenty three deals with design of Cold formed light gauge steel construction. In case of structures of moderate spans and carrying moderate loads, the sections using small thickness are economical. Chapter twenty three to thirty deals with timber and design of timber structures.
- Chapter thirty one deals with multi-storey buildings, while thirty two deals with Pressure Vessels.
- Chapters on Computer aided analysis, multichoice questions and answers and solved problems have been added from the students point of view to give deeper touch to the subject.
- Last but not least, detailed up-to-date, design data tables for references and various design charts have been added to make the volume self contained.
