摘要在许多发展中国家的偏远山区，石材砌筑仍然是一种普遍的做法。实地调查表明，传统的施工方法通常不能为这类建筑物提供足够的抗震能力。本研究旨在调查和改进单层石砌体建筑在极端事件下的安全性、经济性和施工便利性。首先通过实地调查，对现有的施工方法进行了研究，并找出了其不足之处。然后，通过增加钢筋混凝土系梁和系柱，设计改进的石砌体墙体，为砌体提供一定的约束。然后对这些壁的面内行为进行了实验研究。共检测了七个具有不同围板和开口配置的石墙。这些研究揭示了使用钢和混凝土围护构件对改善…
AbstractStone masonry construction is still a common practice in remote mountainous areas of many developing countries. Field investigations have shown that the traditional construction practices do not usually provide adequate seismic resistance for such buildings. This study was carried out to investigate and improve the construction of single-story stone masonry buildings in terms of safety in extreme events, economy, and ease of construction. The current construction methods were first studied through field investigations, and their deficiencies were identified. Then, improved stone masonry walls were designed that provide some confinement for the masonry by adding steel and reinforced-concrete tie-beams and tie-columns. The in-plane behavior of these walls was then studied experimentally. A total of seven stone masonry walls with different configurations of confining elements and openings were examined. These studies revealed the benefits of using steel and concrete confining elements for the improve...
