Celsius® hollow section design vs Structura

This app is designed to help structural engineers to find the right hollow section size for their application. Just enter your design load conditions – ultimate axial load and required buckling length – and this app will calculate which section size, from the comprehensive Celsius® range of structural hollow sections, will best match your application. The app will also select sections for members in bending, based on strength or user‐specified deflection limit. The app will list the sections which meet your criteria, with all the relevant information, including the efficiency factor and mass per metre. Sections are classified relating to their availability in the UK market, so giving you confidence that your selected section will be widely available. Filters may be set to identify sections of a certain size, or utilization. Using the filters, results may be ordered by embodied CO₂, by size or by weight. Want to save your results? Just hold on the selected section and share it by email or any other messaging service. The Celsius range of fully normalized, true hot finished hollow sections from Tata Steel is fully compliant with EN 10210 and CE marked for construction applications. The range covers square, rectangular, circular and elliptical hollow sections from 40x40x4mm to 400x400x16mm and equivalent sizes in other shapes, with circular sections up to 508x16mm.

Structural design for building engineers, to BS 8110-1:1997. Run a whole-building load takedown, design every column in a grid, and get a bar bending schedule and drawings — from your phone, on site or in the office. Built for Nigerian practice, by a COREN civil engineer. WHAT IT DESIGNS • Building takedown — accumulates Gk and Qk from roof through floors, walls and self weights, then designs the typical slab, beam, ground column and footing in one pass • Column grid — every column in a bays × bays grid, classified corner, edge and interior with exact tributary areas, with a plan map of the families • Slabs — one-way and two-way solid slabs, Table 3.13 and 3.14 coefficients, flexure, shear and deflection • Beams — singly and doubly reinforced, shear links, span/depth deflection check • Columns — short columns by equations 38 and 39, slender columns to clause 3.8.3, biaxial bending to 3.8.4.5 • Foundations — pad footings, strip footings under blockwork, and solid rafts • Stairs, lintels • Wind and stability — storey shears, base shear, overturning, sway against h/500 and the P-delta stability index EVERY RESULT IS A CALC SHEET Formula, substituted values, and a PASS or FAIL on each check — not just an answer. Designs that fail say what to change. Every sheet carries its scope and limitations. BAR BENDING SCHEDULES AND QUANTITIES Schedules to BS 8666 with shape codes, cutting lengths and nominal masses. Bills of quantities in concrete, steel, formwork and excavation, priced with your own naira rates. DRAWINGS Foundation layout general arrangement and a detail sheet per member, exported as PDF or DXF for your CAD. PROJECTS AND REPORTS Group designs into client jobs and export a branded PDF report with your practice details and COREN number. Work is stored on your phone, with an optional backup to your account. HOW TALL IT GOES Gravity-only designs stop at four storeys. With wind design, eight — braced walls, a core, or a moment frame. The app tells you which and why, rather than quietly designing something it should not. WHAT IT WILL NOT DO A PASS means the design checks out for the loads you entered, not that a building is safe to build. There is no seismic design, no piled foundation, and settlement is not calculated. Bar bending lengths use simplified anchorage and lap assumptions stated on each sheet. You are the reviewing engineer, and every output says so. FREE AND PAID Single members — slab, beam, column, footing, strip footing, stair, lintel, raft and wind — are free, however many you run. A credit unlocks one project: a whole-building takedown or a column grid. Revising that project, re-running it and re-exporting it are free forever. An unpaid run still shows whether the building passes and every warning with it, so finding out that a design fails costs nothing. Structura is a product of GreatCallie International Ltd.
