CE 405 Design of Steel Structures – Prof Dr A Varma Example 2 2 Design a simply supported beam subjected to uniformly distributed dead load of 450 lbs ft and a uniformly distributed live load of 550 lbs ft The dead load does not include the self weight of the beam Step I Calculate the factored design loads without self weight 2018 01 22 nbsp 0183 32 From steel tables try section 457 x 191 x 82 W pl y 1830 cm 3 CHECK OUT ALSO Design of Steel Beams to BS 5950 – 1 2000 Structural Analysis of Compound Arch Frame Structure Properties h 460 0mm b 191 3mm d 407 6mm t w 9 9mm t f r 10 2mm A 104 cm 4 I y 37100 cm 4 I z 1870 cm 4 W el y 1610 cm 3 W el y 1830 cm 3So if we assume a column size of 300 mm x 600 mm with 1 steel and 2 55 why 2 55 so 3 m column hight – beam size meters standard height the self weight of the column is around 1000 kg per floor that id equal to 10 kN 2020 09 19 nbsp 0183 32 An example of a cantilever beam subjected by loading is shown below Design a suitable UB section in S355 steel Assume the beam is fully laterally restrained Assume self weight of beam is included in the permanent action below 2017 08 01 nbsp 0183 32 Design example A laterally restrained beam 9m long that is simply supported at both ends supports a dead uniformly distributed load of 15 KN m and an imposed load uniformly distributed load of 5KN m It also carries a dead load of 20KN at distance of 2 5m from both ends

IS 808 – Dimensions hot rolled steel beam column channel and angle sections AS NZS 3679 1 – Australia and New Zealand standard Designation and terminology Wide flange I beam In the United States steel I beams are commonly specified using the depth and weight of the beam For example a quot W10x22 quot beam is approximately 10 in 254 mm in depth nominal height of the I Composite Beam – a structural element usually a Beam that is connected to a concrete slab such that the steel and concrete act as one element Compression – the state for example in a column or an element of a truss whereby a member is being shortened by a force Compression is an axial load that is the opposite of tension ASDIP STEEL performs the steel or composite design for multi span continuous beams either interior or border subjected to distributed and concentrated loads as well as moments Two overhangs may be modeled The program computes the bending moments shear forces and vertical deflections per load combination and compares them against the beam strength The Cold Formed Steel Design Manual consists of six Parts This information is supplemental to the 2001 edition of the North American Specification for the Design of Cold Formed Steel Structural Member s Each part in the Design Manual should be used in conjunction with the Specification Commentary and the other parts where appropriate Part I Dimensions and We are designing the beam for gravity loads dead load D and live load L Therefore we can reduce the above combinations to include only these loads 1 1 4D 2 1 2D 1 6L 3 1 2D L 4 1 2D L 5 1 2D L 6 0 9D 7 0 9D By inspection load case 2 will create the largest load This load case is selected as shown in the table above 4

Steel roof and floor deck diaphragm design requires careful attention to load paths stiffness variations fastener types and regional preferences Figure 1 In its most basic form a diaphragm behaves as if it were a short deep beam Shear diaphragms are commonly used in buildings as a means of transmitting lateral loads In building design these loads are typically caused by wind Special Steel Beam Connections This type of connections is used for the case where the arrangements of the structural element are in such a way that standard connections cannot be used For example intersection angels might be different by a certain degree and when beam centers offset from column centers If two layer of steel bars are placed in a beam then the distance between them shall not be less than 25 mm Concrete protection for reinforcement the designer must maintain minimum thickness or concrete cover outside of the outermost steel to provide the steel with adequate concrete protection against fire and corrosion According to ACI Code 7 7 concrete cover of 40 Example 10 Design of a Beam Bearing Plate Example 11 Design of a Column Base Plate Beam Columns Members Example 1 Determining which AISC Specification interaction equation is applicable for a given beam column and checking adequacy Example 2 Analysis of steel beam column braced against sideswayWorked Example – 5 Made by SRSK Date 01 10 00 Structural Steel Design Project Calculation Sheet Checked by VK Date Design Example 5 Design a bolted web cleat beam to column connection between an ISMB 400 beam and an ISHB 200 40 kg m column The connection has to transfer a factored shear of 150 kN Use bolts of diameter 20 mm and grade 4 6

2018 08 29 nbsp 0183 32 General Design A castellated beam is a beam that has a regular and repeating pattern of hexagonal holes It is created by cutting the pattern lengthwise across two different halves offsetting and then welding them together to create a single expanded beam These beams have been used in various construction projects since the second half of the twentieth 1 10 Vertical Parabolic Curve Equal Tangent Example 2 DESIGN DATA 2 1 Seismic Zone – LRFD Bridge Design Specifications 2 2 Soil Profile Types 2 3 Design Traffic Lane 3 MATERIAL 4 PRELIMINARY DRAWINGS 4 1 Example Preliminary General Drawing Sheet 1 of 2 4 2 Example Preliminary General Drawing Sheet 2 of 2 4 3 Construction Limits Sketches for Bridges and Example 11 Design of a Column Base Plate A W10 x 49 column is supported by a concrete pier whose top surface is 19 inches x 19 inches Design a base plate given that the column dead load is 100 kips and live load is 150 kips Base plate material is A36 steel and concrete compressive strength is 3 ksi In cold formed steel design it is often not practical to provide load bearing and end bearing stiffeners This is always the case in continuous sheeting and decking spanning several support points The depth to thickness ratios of the webs of cold formed members are usually larger than hot rolled structural members In many cases the webs are inclined rather than vertical 2020 11 23 nbsp 0183 32 Example of a simple steel beam design done as a practicing engineering The reason I m not checking the shear resistance is because I know that bending and d
