Abstract
A central opening strut system is used to support a diaphragm wall for foundation excavation. This system contains at least one regular polygon module and a number of straight strut members. These strut members connect the diaphragm wall and the regular polygon module together, so that the earth pressure acting on the diaphragm wall in one direction can be transmitted to the diaphragm wall in the other directions by the arch action of this polygon module. In this research, the basic structural behavior of the central opening strut system is examined. A full-scale structural testing of the joint subassemblage is also performed to examine the ultimate strength of the joint. A construction site with five excavation stages and four layers of strut systems is chosen as the case study. The ABAQUS finite-element program is employed in the study of the behavior of this system during various construction stages. From these studies, it is found that the proposed central opening strut system is able to provide a large working space and greatly increases the efficiency of the construction work. Through proper design of the member and the joints, this system provides a better safety factor as compared with the traditional strut system.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
