Specifies the soil type as defined in the following table:
|
I Hard Soil |
Ground deposits formed exclusively by layers with propagation velocity bo = 700 m/s or modulus of rigidity >= 85000 t/m2 |
|
II Med. Soil |
Ground deposits with fundamental period of vibration and effective velocity of propagation which meets the condition: bcT5 + b5Tc > bcTc |
|
III Soft Soil |
Ground deposits with fundamental period of effective vibration of propagation which meets the conditions: bcT5 + b5Tc < bcTc |
