IntroductionThe aim of presenting these tables is to provide the structural engineers withwide range of information required in designing steel structures. Previously,a steel designer had to search in many tables, handbooks, manuals, etc. tocollect the necessary information needed to complete his/her design.These tables are divided into nine chapters. Chapter one provides thegeometrical properties of common hot rolled sections which includes thefollowing: Equal and unequal angles: primarily used in trusses for resistingaxial forces. Channels (UPN): used as truss members and purlins or side girts. I-sections (IPN, IPE, HEA, HEB, HEM):IPN section is suitable for beam subjected to bending moment aboutits major axis.IPE section used mainly for beams or beam column.HEA, HEB, and HEM sections are primarily used for memberssubjected to bi-moments or for heavy beam-columns. T-sections are produced by cutting I-sections into two halves. Theyare used as brackets, truss members or light beams.iii
Pipes and hollow sections: primarily used as truss members inwelded trusses.Hollow square and rectangular sections, sometimes used as roofpurlins or light beam-columns. Flat plates used in connections as head plates, gusset plates or it canbe utilized in composing built-up section. Rails: used mainly in tracks of moving structures such as cranebridge.In unprecedented presentation of section properties in the Egyptian practice,Chapter two introduces the geometric properties for combined hot rolledsections and built–up welded sections.This chapter provides the properties for the following combined sections: Two equal or unequal angles back to back:Used mainly as lower or upper chord of trusses, or bracing members. Two channels back to back:Used mainly as lower or upper chord in heavy trusses. Two channels toe to toe:Used as beam-column especially when the buckling lengths in-planeand out of plane are nearly equal.iv
IPE and UPN:This section is used primarily as section for crane girders. The“UPN” section is provided at the top flange where the lateral shockof the crane bridge is applied. Symmetrical welded I-Section:This section consists of three parts welded to form symmetricalI-sections. It is used mainly for beams or beam-columns. Unsymmetrical welded I-sections:This section is formed in away to make the upper flangeapproximately twice the lower flange. Thus it is suitable for cranegirders where the lateral shock is applied at the upper flange. Thesection might also be used for composite construction when theupper and lower flanges are switched.Chapter three introduces the geometrical properties of cold-formed steelsections, these sections includes: Channels (stiffened and unstiffened) and Z sections (with straightlips and with inclined lips): These sections are used mainly for roofpurlins and side girts. Sometimes, they can be used in light trusses asweb members.v
Chapter four provides the geometrical properties for combined cold-formedsections. These sections includes: Two channels back to back:Used as lower or upper chord in light trusses or in bracing members. Two channels toe to toe:Used in light beam columns or as eave struts I bracing system.Chapter five provides complete information about the size, weight, and griplength of ordinary and high strength bolts. It also provides the dimensionand weight of washers and nuts used for each type of bolts.This chapter also includes the dimension and the weight of anchor boltswith various configurations.Chapter six provides the geometrical properties of sample of corrugatedsheets whether they are single layer, sandwich panels, or metal decking steelsheets. In this chapter the allowable spacing between purlins is alsoprovided based on the strength and serviceability criteria.Chapter seven includes samples of the wheel loads of crane bridgescovering the following ranges of crane capacities: Light cranes with capacity range from 0.5 to 6.3 ton. Normal cranes with capacity range from 2.0 to 25 ton. Heavy cranes with capacity range from 25 to 63 ton.vi
Chapter eight provides the common symbols used in welding constructions.Chapter nine includes various data covering the following areas: Conversion tables used to convert engineering units from imperial toSI or metric systems and vice versa. Dimensions of aircraft with various types to assist in choosing theconfiguration of aircraft hangar. Geometrical properties of common shapes in engineering practice.vii
