Small unshaped log residence of V-shaped wall crosssection, which is fit for manual-making on site, can accelerate construction speed and has a good wall stability and seismic resistance.
Steel components in the configuration section, so that the structure has a cross-section of small components, large capacity, good seismic performance, the advantages of easy construction;
构件截面中型钢的配置，使结构具有构件截面小、承载力大、抗震性能好、方便施工的优点；
