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...

Konw the 10 best ways to optimise structural design of single/multi storey wide span PEB ( Pre Engineered Buildings). See the following images to have an idea about application of PEB structures. PEB Wide Span Building PEB Aircraft Hangar PEB Large Span Warehouse PEB Multistorey Apartment PEB Multistorey Commercial These tips are to be discussed with Architect/Client while seeking approval of GAD and design process: 1. Keep End Bay Spans 0.70times of Interrior Bay Spans : With this approach, you may reduce size of both purlins and girts designed  as continuous flexure member with overlaps at interrior supports. Same duplicatable size and thickness of cold form sections give good economy. 2. Use web-tapered I sections for SWC (Side Wall Columns) and CHS/SHS/RHS ie closed tube sections for IC (Interrior Columns). Interrion Columns are bracing-free so require small l/r to use full capacity. 3. Use SSR (Standing Seam Roof) Sheeting on roof : The fixings with the Purlins are screwless h...
