Barrage

Barrage

(OP)
Hello I am sandeep. I have some queries in Abaqus. Please clarify my queries. I am working on analysis and design of barrage which include raft and piers. I modeled barrage in autocad-3D and imported it as parts ( part1- pier and part2- raft and part3-soil). These parts are connected using tie constraints. Following are my queries

1. Does Abaqus give stress values at tie constraints (i.e., boundary conditions)larger values than what exactly they are? If so how can I get exact values?

2. In response spectrum analysis the values of stresses (S11, S22 & S33) at all points are obtained as positive. So how can I know which is compressive and which is tensile stress

3. In response spectrum analysis, for a particular path along the thickness of section (pier or raft), how can I know compressive stress at one end of the path when other end is in maximum tension.
