No. of exhibition	Goal of the construction completion
Exhibition D	(1) The average value of the vertical displacement of the top node of the main bearing structure is close to 0 mm.
	(2) The stress level of the main bearing structure should be as low as possible.
	(3) The vertical displacement of the self-anchored stocks’ ends of the main bearing structure is close to 0 mm.
	(4) The midspan vertical displacement of the secondary bearing structure is close to 0 mm.
	(5) The stress level of the secondary loadbearing structure should be as low as possible.

In this paper, “construction completed state” is defined as cable tensioning, main purlin and roof installation, support unloading, and swing column installation are completed.
