Week 11 Challenge
Introduction
This design note pertains to the design of abutment with elastomeric bearing.
Structural skew angle is 0o
The substructure consists of RCC wall type abutment and circular type on pile foundation. Following components of substructure and foundation are designed.
Loads
1.Dead load (Due to self weight of superstructure, substructure, foundation and soil weight)
2.Superimposed Dead load (SIDL) excluding wearing course due to crash barrier.
3.Superimposed Dead load (SIDL) due to wearing course.
4.Carriageway live load
1Lane of 70R Wheeled
1Lane of class A
2Lane of class A
5.Seismic Load
6.Wind Load
7.Earth Pressure
1) Design the pile of the below mentioned bridge, considering 28 m straight span.
a.With abutment having backfill
For to retain back fill wall type abutment is recommended. Following is the procedure -
Design the pile of the below mentioned bridge . considering 28 m straight span.
b.With abutment having RE wall.
Cirular type abutment taken in consideration as earth pressure is not effective on abutment. Rest process as follows-
2) Different components of pile foundations and calculate kg/cumec (poundage) steel quantity in the pile.
Component of pile foundation - Pile and pile cap
