Experimental Study on Stability of Long-Span PC Cable-Stayed Bridge during the Construction Periods

Table 2

Experimental conditions.

Experimental conditions	Load cases	Load configuration
The first load	100% times loading	The tower has a weight of 510 kg. The main beam is loaded with a total of 455 kg
The second load	Midspan + hanging basket	At the end of the midspan, a weight of 5.7 kg is used to simulate the hanging basket, when the main beam is asymmetrical
The third load	Midspan + hanging basket side span + hanging basket + closure segment	A 10.7 kg weight is added to the end of the side to simulate the hanging basket and the closing section
The fourth load	200% times loading	Remove the load applied for the second and third times and then load 500 kg symmetrically on the main beam
The fifth load	300% times loading	Load 500 kg symmetrically on the main beam
The sixth load	400% times loading	Load 500 kg symmetrically on the main beam
