Research on production process optimization of precast Concrete Component factory based on value stream mapping
Engineering Construction and Architectural Management, 2019Co-Authors: Shuqiang Wang, Jia Tang, Yiquan Zou, Qihui ZhouAbstract:The purpose of this paper is to investigate the process optimization of a precast Concrete Component production line by using value stream mapping.,This paper is an empirical focused on of lean production theory and value stream mapping. The data in the case study were collected in real time on-site for each process during the production process of a prefabricated exterior wall.,The results of the current value stream map indicate that the main problems of the current production process are related to equipment, technology and organization. The equipment problems include simple demolding and cleaning tools and the lack of professional transfer channels. The technology problems include the lack of a marking mechanism and pipeline exit mechanism. There is a lack of standard operating procedures and incomplete process convergence. A comparison and analysis of the current value stream and the future value flow indicate that optimizations of the process flow, the production line layout, and the standard operating procedures have shortened the delivery cycle, reduced the number of workers, improved the operator’s operating level and balanced the production line.,The results of this study provide practitioners with a clear understanding of the optimization of the precast Concrete Component production and represent a method and basis for the process optimization of a factory production line; the approach is suitable for process optimization in other areas.,This research represents an innovative application of lean production theory and value stream mapping in a complex production line of precast Concrete Components and thereby fills the gap between the theory and practice of the optimization of a precast Concrete Component production line.

seismic shear strength of reinforced Concrete columns
Journal of Structural Engineering-asce, 1994Co-Authors: M Nigel J Priestley, Ravindra Verma, Yan XiaoAbstract:Aspects relating to the shear strength of circular and rectangular columns under seismic loading are presented. An examination of existing design equations reveals wide differences in predicted responses. Particular emphasis is placed on models capable of representing the interaction between flexural ductility and shear strength. A simple method is proposed whereby the strength enhancement provided by axial compression is separated from the Concrete Component of shear strength and considered to result from arch action. The strength of the Concrete Component is reduced as flexural displacement ductility increases. Prediction of shear strength from the proposed and alternative methods are compared with results from a wide range of tests of columns failing in shear. The proposed method is shown to provide significantly improved correlation with experimental results. Conservative modifications are made to enable the method to be used for design.
