Subject: ductility of the wall Скажите, пожалуйста, что такое здесь ductility ?может, податливость, подвижность? ( Prefabricated wall and assembly structure for prefabricated building, and construction method therefor) СпасибоIn practice, cracks often spread around from grouting holes or air outlets, and there is a phenomenon that concrete falls off as a whole here. In addition, the outer diameter of the grouting sleeve is large, ranging from 4-5cm, and the outer surface of the grouting sleeve is generally smooth at present, which may not form an effective constraint with the surrounding concrete. Therefore, in the later stage of the project, large concrete blocks at the bottom often fall out and the effective compression area at the bottom decreases, so the assembly structure itself may affect the bearing capacity of the wall in the later stage and reduce the ductility of the wall.
