The 3 secret technical tips for optimised steel concrete composite floor beams are discussed below for the benefit of steel designers. These are particularly applicable for commercial buildings, storage spaces, departmental shops , car park etc with more column-free areas. The tips to enjoy major advantages of composite steel beam over naked steel beam for the same span and loading are as below: Tip#1 As a flexure/bending member, the least section area for a naked steel beam happens when the web area equals half of total area of section and other half are is equally distributed in top and bottom flanges. Thus Atotal = 2Aw, and Aw=2Af where Aw is the area of web, Af is the area of each of top and bottom flange to resist design moment, ie. A =Aw+2Af. In other words, web resists 25% of BM and each of Flange resists 75% of BM either in compression or tension. Of course, serviceability criteria to be looked into separately by providing appropriate second moment of inertia (I) required for r...

The 7 Advantages of Precast Concrete Smart Pavements Over Ashphalt Roads are listed below. But before we delve into the topic of removable precast concrete roadworks, let us see what makes precast concrete pavement much supirior to conventional ashphalt pavement in roadworks: Economic Advantages: Higher Durability: Concrete roads can be designed for 50 years or more, and they last around three to five times longer than asphalt roads before a first major rehabilitation is required.The superior durability of concrete over asphalt ensures minimum and predictable maintenance costs. USA and Germany are the front runners in using concrete pavements over ashphalt pavements. Less Maintenance: While asphalt requires regular maintenance and frequent reconstruction, concrete will last for decades with relatively minor repair. Every time you need to repair a pavement you need to close at least one lane, causing traffic congestion, lost time, and an additional danger of accidents. Competetive Initi...

The 5 Best Technical Advantagess of Cellular PEB Structures for Economy, Strength and Serviceability are listed below. Before we come to technical advantages that the cellular beams enjoys over solid web I sections, remember that cellular beams are usually desirable in places where there are services below the ceiling and the openings in cellular beam allow services to pass through without increasing the floor height or building height. Architects also prefer this type of members due to their aesthetic look.  What is Cellular Beam? Cellular beam is an improved version of the castellated beam prepared from rolled steel I-beam/built up I beam (prefabricated in PEB frames with high tensile steel grades) with circular perforations in the web. Comparing the cutting pattern of castellated members, cellular members have more flexibility in their finished depth, perforation diameter and spacing. In addition, cellular members need less infill plates and easier infill cut parts compared...

Do you dare to design a Suspension Bridge? It is an ultimate dream!! Many structural engineers dream to evolve a design of at least one Suspension Bridge which would be a national landmark bringing prestige and fame to a country where they belong. Suspension Bridges are economical for main span (central distance between the Pylons or Towers) beyond 500m. For your reference, listed below are the top 12 longest Suspension Bridges of the world in ascending order but there is stiff competetion amongst countries to topple one another for the top position. Just imaging the length of main span constructed so far and opened for traffic as a marvel. Chinese bridges are listed in 6 amongst top 12 suspension bridges in the world. Just Google to find out more information about them. #12.  Yavuz Sultan Selim Bridge, Turkey : Width 58.4m, Main Span 1408m, Year Opened 2016 Yavuz Sultan Selim Bridge, Turkey #11. Humber Bridge, United Kingdom : Width 28.5m, Main Span 1410m, Pylon Height 155.5m Yea...

The 10 techno-economic advantages of using steel tubes (hollow sections) in structural application when compared with traditional stand alone either open-section steel or concrete structures are given below near the end of article. Design is an interactive process between the functional and architectural requirements and the strength and fabrication aspects. In a good design, all these aspects have to be considered in a balanced way. But before we come into that, see the following images where steel tubular sections were used in structural applications for hallmark buildings and bridge construction. Simply google to find more information about these structural engineering marvels where steel tubes were extensively used. Centre Pompidou, Paris Centre Pompidou, Paris : Rare Architectural marvel with all visible services on exterior face marked with distunguished coloures (mechanical, electrical, water suppy, plumbing, and steel superstructure with structural tubes). There are four baseme...

Here are the 10 Incredible Benefits of Composite Construction in Steel Intensive Multistorey Buildings as below. The following images would give you some idea about composite design of multistorey buildings. Composite Construction Long Span Structure Girder Slab Composite Construction Composite Multistorey Building Composite construction has contributed significantly to the steel intensive construction in the commercial and industrial building sector in India. The main benefits of composite construction are: 1. Speed of construction Bundles of decking can be positioned on the structure by crane and the individual sheets then installed by hand. Using this process, crane time is minimal, and in excess of 400 m2 of decking can be installed by one team in a day, depending on the shape and size of the building footprint. The use of the decking as a working platform speeds up the construction process for trades and services to follow next. Minimal mesh reinforcement is required (often el...
