To integrate seismic resistance of adobe structure, the combination of external reinforcement by the fiber net and fiber reinforced mud plaster was studied. The aim of tow method is both to increase the strength of structure and to decrease the initial cracking of mud plaster. Static bending test of adobe column and drawing test of strings from mud plaster were done to build the relational expression for earthquake performance of reinforced adobe structure. As a result, the required amount of strings can be determined for many materials. The fixing ability of fiber reinforced mud plaster is not enough to resist at the yielding failure state of adobe structure. To integrate the fixing, wire binding through wall or column is good enough.

为了提高土坯结构的抗震性能，研究了纤维网与纤维增强泥灰膏相结合的体外加固方法。两种方法的目的都是为了提高结构的强度和减少抹灰的早期开裂。通过土坯柱的静曲试验和泥膏拔弦试验，建立了土坯结构抗震性能的关系式。因此，对于许多材料，可以确定所需的串量。纤维砂浆的固定能力不足以抵抗土坯结构的屈服破坏状态。为了使固定更完整，穿过墙壁或柱子的铁丝捆绑就足够了。
