Prefabricated Concrete Component Geometry Deviation Statistical Analysis

Table 7

KS inspection result of size deviation.

Prefabricated components	Project	Normal distribution		Weibull distribution
		Prefabricated beam member	Length	0.038	0.592	0.213	0.039
Width	0.177		0.187	0.098	0.028
Height	0.044		0.331	0.052	0.311
Prefabricated column member	Length	0.073	0.429	0.189	0.033
	Width	0.098	0.373	0.167	0.048
	Height	0.031	0.333	0.094	0.309
Prefabricated wall panel components	Height	0.055	0.419	0.193	0.037
	Width	0.061	0.380	0.313	0.018
	Thickness	0.035	0.377	0.051	0.293
Prefabricated composite slab	Length	0.087	0.199	0.199	0.038
	Width	0.019	0.211	0.227	0.031

Since the thickness direction of the prefabricated composite slab is cast-in-place concrete, it was not counted.
