Current discrete/lattice methods can simulate a continuous mechanical behavior thanks to a network of bonds. The main drawback of these approaches is the need of a calibration process to link the emerging behavior of the structure and the parameters of the local mechanical bond. It is proposed in this work to use a fast and recent reduction model technique to build once and for all an exhaustive data chart and thus to avoid the calibration process. The proper generalized decomposition technique was used to build a parametric analysis in the case of a lattice beam structure. The results were in the range of the current calibration values found in the literature and extend it by giving a global calibration curve. They also allowed to discuss about the influence, in this specific case of lattice-beam structure, of the density of beams in terms of number of discrete elements and connectivity.

由于键合网络的存在，当前的离散/晶格方法可以模拟连续的机械行为。这些方法的主要缺点是需要校准过程来将结构的新出现的行为与局部机械键的参数联系起来。在这项工作中，建议使用一种快速且最新的简化模型技术来一劳永逸地构建详尽的数据图表，从而避免进行校准。在晶格梁结构的情况下，使用适当的广义分解技术来建立参数分析。结果在文献中找到的当前校准值范围内，并通过给出全局校准曲线对其进行扩展。他们还允许讨论这种影响，在这种特定的格梁结构情况下，
