Steel Beam-Precast Slab Floor System: A Darling Structural System for Multi-storey Apartments, Condominiums, Hotels, Campus Housing. Steel beam-precast plank system is a nice repalcement of conventional RCC flat slab system. This system is based on fast track, dry, environment friendly construction giving early return on investments achieving goals with the following characteristics: Economical Reduced dead load on structure and foundation Non-proprietary system (see reference to download free design guides) Fast construction (the beam-plank system is ready by 60 days for medium rise buildings) Lower floor-to-floor height (as low as 8' ceiling height) Savings on HVAC, vertical finishes, MEP services Accommodation of other trades to permit fit-out on lower levels while building above Easy accommodation of alternative facade systems Open space on ground No transfer girders Flexibility to permit architectural expression Dry mix use construction with minimum westage and pollution at si...

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 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...
