加速度

A: Acceleration is the rate of change in velocity of the ground shaking (how much the velocity changes in a unit time), just as it is the rate of change in the velocity of your car when you step on the accelerator or put on the brakes.

答：地震加速度是地壳震动速度的变化率（在单位时间内速度改变量），就像你踩下油门或者刹车以后，你的汽车的速度变化率。

Finally, a practical seismic analysis method is presented. Through a reasonable assumed distribution of lateral forces, the capacity curve can be derived from the story shear-displacement curves. And by using equations suggested by ATC-40, the corresponding capacity spectrum, period, damping ratio and PGA can also be obtained. This method can provide not only collapse PGA of a low-rise RC building structure, but also damage conditions of members at a specific PGA. Combining with the deterioration rule for RC column after multiple earthquakes, it can also be applied to seismic analysis for after-earthquake or aged buildings.
