Research on earthquake resistant adobe structure by using combination of fiber reinforced plaster and fiber strings

为提高土坯结构的抗震性能，研究了纤维网与纤维增强泥浆相结合的体外加固方法。两种方法的目的既是为了提高结构的强度，又是为了减少泥浆的初始裂缝。通过土坯柱静力弯曲试验和泥浆拉拔试验，建立了加固土坯结构抗震性能的关系式。结果，可以为许多材料确定所需的串量。在土坯结构屈服破坏状态下，纤维增强泥浆的固结能力不足以抵抗。要使固定一体化，通过墙或柱的钢丝捆绑就足够好了。

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.
