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...
