In all projects, he performed scaled model tests to assess the three-dimensional structure behaviour. To do so, he developed instruments to measure and register deformations and displacements, namely contact strain gauges that were pressed against the model, with no need to be glued, enabling their reuse in any section (the electric gauge was glued to a thin rubber, which was glued to an acrylic plate). In 1950, he constructed an “auto-influenciograph” (equipment that could automatically register the influence lines of the response of the structure due to a load that follows a trajectory over the deck and a paper strip that moves in synchrony with the applied load). With such models, he could access the response of high hyperstatic continuous structures that could not be analytically modelled in the 1950s and 1960s.

在所有项目中，他都进行了比例模型测试以评估三维结构行为。为此，他开发了测量和记录变形和位移的仪器，即压在模型上的接触应变计，无需粘合，使其能够在任何部分重复使用（电子计粘在薄橡胶上，粘在亚克力板上）。1950 年，他建造了一个“自动影响仪”（可以自动记录结构响应的影响线的设备，该设备由于沿着甲板上的轨迹的载荷和与施加的载荷同步移动的纸条而引起的结构响应的影响线） . 有了这样的模型，他可以访问在 1950 年代和 1960 年代无法进行分析建模的高超静力连续结构的响应。
