A New Formulation on Seismic Risk Assessment for Reinforced Concrete Structures with Both Random and Bounded Uncertainties

Table 1

Threshold capacity values of interstory drift and peak floor acceleration.

Threshold capacities of  both the EDPs	NO level		IO level		LS level		CP level
	Mean	SD^1	Mean	SD^1	Mean	SD^1	Mean	SD^1
Interstory drift threshold		0.002		0.005		0.015		0.025
Acceleration threshold		0.4		0.6		0.8		1.2

1: standard deviation of the interstory drift threshold and acceleration originated from Sun et al. [53].
