Bamboo structures — Bamboo culms — Structural design 竹 - 结构设计
发布日期: 2021-06-03
本文件适用于主要承重结构由圆竹制成的竹结构或框架构件由圆竹制成的剪切板系统的设计。 条款中规定的除外?12、本文件适用于不超过7层的一层和两层住宅、小型商业或机构及轻工业建筑?米高。 本文件仅涉及竹结构的机械阻力、适用性和耐久性要求。 本文件允许竹结构设计采用允许承载能力设计(ACD)和/或允许应力设计(ASD)方法。允许承载能力和允许应力方法可以在同一结构中组合使用。 本文件还认可了基于部分安全系数设计(PSFD)和/或负载和阻力系数设计(LRFD)方法的设计方法(5。11.1)、先前已建立的经验(5.11.2)或记录的“试验设计”方法(5.11.3)。 不考虑其他要求,例如关于隔热或隔音的要求。竹结构可能需要考虑超出本文件范围的附加要求。在影响符合此处包含的设计要求所需的建筑材料和产品质量的范围内,执行被涵盖。 本文件提供了许多修改因子,指定为Ci。这些是基于最佳可用工程判断的经验得出的因素,被认为普遍适用于适用于建筑施工的竹材料。影响竹材料性能的参数很多,通过使用实验确定的强度和刚度特征值来明确解决。附件?a概述了制定本文件条款的依据。 本文件不适用于 —?由工程竹制品制成的结构,如胶合层压竹、交叉层压竹、定向股或致密竹材料, —?竹子不是主要承重成分的竹子增强材料。这包括竹钢筋混凝土、砖石和土壤, —?用竹子建造的脚手架结构。
This document applies to the design of bamboo structures whose primary load bearing structure is made of round bamboo or shear panel systems in which the framing members are made from round bamboo. Except as indicated in Clause 12, this document applies to one- and two-storey residential, small commercial or institutional and light industrial buildings not exceeding 7 m in height. This document is concerned only with requirements for mechanical resistance, serviceability and durability of bamboo structures. This document permits an allowable load-bearing capacity design (ACD) and/or allowable stress design (ASD) approach for the design of bamboo structures. Allowable load-bearing capacity and allowable stress approaches may be used in combination in the same structure. This document additionally recognises design approaches based on partial safety factor design (PSFD) and/or load and resistance factor design (LRFD) methods (5.11.1), previous established experience (5.11.2), or documented ‘design by testing’ approaches (5.11.3). Other requirements, such as those concerning thermal or sound insulation, are not considered. Bamboo structures may require consideration of additional requirements beyond the scope of this document. Execution is covered to the extent that it impacts the quality of construction materials and products required to comply with the design requirements contained herein. This document provides a number of modification factors, designated Ci. These are empirically derived factors, based on best available engineering judgement, that are believed to be universally applicable to bamboo materials that are appropriate for building construction. Parameters affecting bamboo material performance are many and are addressed explicitly through the use of experimentally determined characteristic values of strength and stiffness. Annex A provides a summary of the bases upon which the provisions of this document were developed. This document does not apply to —    structures made of engineered bamboo products such as glue-laminated bamboo, cross-laminated bamboo, oriented strand, or densified bamboo materials, —    bamboo-reinforced materials where bamboo is not the primary load-bearing constituent. This includes bamboo-reinforced concrete, masonry and soil, or, —    scaffold structures constructed with bamboo.
