本文研究了在既有砖房中采用钢拉结连接墙体对抗震性能的影响。三个模型的简单的两层砖砌体房屋与木地板，有或没有墙的联系，已经测试了一个简单的地震模拟器。此外，还介绍了一种结构型式相同，但钢筋混凝土结构型式不同的模型。地板而不是木地板，已经进行了测试，以进行比较。虽然木地板与托梁没有固定在墙上并不能防止分离和解体的墙壁，刚性板和钢结显着改善抗震性能。根据试验结果，提出了一种简单的拉杆设计方法。
The influence of tying the walls with steel ties on the seismic behavior of existing brick-masonry houses has been investigated. Three models of simple two-story brick masonry houses with wooden floors, with or without wall ties, have been tested on a simple earthquake simulator. In addition, a model with identical structural configuration, but with r.c. slabs instead of wooden floors, has been tested for comparison. Whereas wooden floors with joists not anchored to the walls did not prevent separation and disintegration of the walls, rigid slabs and steel ties significantly improved seismic behavior. On the basis of test results, a simple method for designing the ties has been proposed.
