Strength, functionality and beauty are the three qualities identifying well-designed architecture. For buildings in earthquake-prone countries such as Japan, emphasis on seismic safety frequently leads to the sacrifice of functionality and beauty. Therefore, it is important to develop new structural technologies that can ensure the seismic performance of a building without hampering the pursuit of functionality and beauty. The moment-resisting frame structures widely used for buildings in Japan are likely to experience weak-story collapse. Pin-supported walls, which can effectively enhance the structural story-by-story integrity of a building, were introduced to prevent such an unfavorable failure pattern in the seismic retrofit of an eleven-story building on a university campus in Tokyo, while also greatly aesthetically enhancing the façade of the building. The slight damage observed and monitoring records of the retrofitted building during the 2011 Tohoku earthquake in Japan demonstrate that the pin-supported walls worked as intended, protecting the building and guaranteeing the safety of its occupants during the earthquake.
强度、功能和美观是鉴定优秀设计的三个关键要素。对于像日本这样地震多发国家的建筑来说，强调抗震安全性往往会导致牺牲功能和美观。因此，开发新的结构技术以确保建筑物的抗震性能而不影响对功能和美观的追求是很重要的。在日本广泛应用于建筑物的抗侧力框架结构可能会出现薄弱层倒塌的情况。在东京一所大学校园的一栋十一层建筑物的抗震加固中，引入了可有效增强建筑物结构逐层层间整体性的销支剪力墙，从而防止出现这种不利的破坏模式，同时大大增强了建筑物的外观美感。在日本 2011 年东北地震中，对加固后的建筑物进行的轻微损坏观察和监测记录表明，销支剪力墙发挥了预期的作用，保护了建筑物并确保了建筑物在地震中的人员安全。
