This paper presents an innovative and sustainable timber constructive system that could be used as an alternative to traditional emergency housing facilities. The system proposed in this study is composed of prefabricated modular elements that are characterized by limited weight and simple assembly procedures, which represent strategic advantages when it comes facing a strong environmental disaster (e.g. an earthquake). The complete dismantling of structural elements and foundations is granted thanks to specific details and an innovative connection system called X-Mini, capable of replacing traditional anchoring devices (i.e. hold downs and angle brackets) by resisting both shear and tension loads. This constructive system, denoted as Hybrid Timber Frame (HTF), takes advantage of the strong prefabrication, reduced weight of light-frame timber systems, and of the excellent strength properties of the Cross Laminated Timber (CLT) panels. Specifically, the solid-timber members typically used in the structural elements of light-frame systems are replaced by CLT linear elements. The results of experimental tests and numerical simulations are critically presented and discussed, giving a detailed insight into the performance of the HTF under seismic conditions.

本文提出了一种创新和可持续的木材建设体系，可以替代传统的紧急住房设施。本研究中提出的系统由预制的模块化元件组成，这些元件的特点是重量有限且组装过程简单，当遇到严重的环境灾难（例如地震）时，这具有战略优势。由于具体细节和称为X-Mini的创新连接系统，完全可以拆除结构元件和基础，该系统能够通过抵抗剪切力和拉力载荷来代替传统的锚固设备（例如，压脚和角钢）。这种建设性的系统称为混合木材框架（HTF），它利用了强大的预制能力，减轻了轻型框架木材系统的重量，并降低了交叉层压木材（CLT）面板的出色强度性能。具体地，通常用在轻框架系统的结构元件中的实心木材构件被CLT线性元件代替。批判性地介绍和讨论了实验测试和数值模拟的结果，从而深入了解了地震条件下HTF的性能。
