2019年2月8日 · Having trouble understanding steel beam references on construction drawings? We explain what all those numbers and acronyms mean. 1. 'Open' Steel Sections. (Universal Beam [UB] Universal Column [UC] and Parallel Flanged Channel [PFC]) Nominal Size vs. Actual size of open sections.

Explore the area moment of inertia (second moment of area) with detailed formulas, calculation tools, and reference tables for common shapes. Essential for structural and mechanical engineering applications. Calculate beam load and supporting forces. Supporting loads, moments and deflections. Stress, deflections and supporting loads.

2024年2月27日 · UB系列（Universal Beam，通用梁）： 特点：UB系列的H型钢具有较窄的翼板和较宽的腹板，这种结构使其特别适合承受纵向拉力和弯曲力。 UB型钢的截面形状呈"H"字形，上下翼缘宽度相等，腰板厚度较薄。

Material to EN 10025-2:2004 Dimensions and properties to BS4-1:2005

The webpage provides section properties, dimensions, and properties for universal beams according to Eurocode 3 and the UK National Annex.

Guidance on the stability of curved rafters in portal frames is given in SCI P281. Alternatively, the rafter can be fabricated as a series of straight elements. It will be necessary to provide purlin cleats of varying height to achieve the curved external profile.

2023年7月24日 · UB型号指的是均布梁，也称为宽翼梁；UC型号则指的是均布柱，也称为宽翼柱。 两者的命名方式为型号+截面高度（mm）+螺纹尺寸（kg/m）。

The following design data to Eurocode 3 (in accordance with the UK National Annex) is available: Section properties: Dimensions & properties Detailing & fire parameters Effective section properties: Compression - S275 Compression - S355 Compression - S460 Axial compression: With S275 With S355 With S460 Buckling resistance moment: With S275 With S355 With S460 Web bearing & buckling: With S275 ...

A 457 x 191 x 67 UB in steel grade S355 is to be used under the three conditions described below. Classify the section for each case and evaluate the local cross- sectional resistance.

UB型英标H型钢是一种主要用于建筑 钢筋混凝土结构 的高强度钢材。 它的截面形状相对简单，易于加工和焊接，而且具有较高的强度和韧性，能够提供更好的 抗剪切 和抗疲劳性能。
