Abstract

A transversely isotropic structural model for wood, based on a polytope strength criterion, is proposed and deployed in the analysis of solid wood columna-capreoli A-trusses reproducing the geometry and connection details of those currently erected in the Aula Magna of the Monastery San Lorenzo ad Septimum in Aversa. The predictivity of the polytope strength criterion is assessed verifying its capability of identifying the closest crisis mode against experimental evidence from a simple flexural test, with minimal wood sacrifice. The model is employed in parametric optimization analyses to infer a design provision for the columna-capreoli connection which appears to be in reasonable agreement with the rule of the art empirically inferable from the observation of many samples of open-node King Post A-trusses belonging to the architectural heritage in Campania of historical and artistic value. A final discussion examines a perspective of extending these optimization analyses to the sustainability of the built environment.

了解柱廊式木桁架过去的技术规则

根据多面体强度标准，提出了一种横向各向同性的木材结构模型，并将其应用于实木柱帽式 A 型桁架的分析中，该模型再现了阿韦尔萨圣洛伦索修道院大广场目前所建桁架的几何形状和连接细节。对多面体强度标准的预测能力进行了评估，根据简单抗弯试验的实验证据，验证了其识别最接近危机模式的能力，并将木材牺牲降到最低。在参数优化分析中使用了该模型，以推断柱帽连接的设计规定，该规定似乎与通过观察坎帕尼亚具有历史和艺术价值的建筑遗产中的许多开节点王柱 A 型桁架样本而经验推断出的艺术规则有合理的一致性。最后的讨论探讨了将这些优化分析扩展到建筑环境可持续性的角度。
