User's Guide: Computer Program for Design and Analysis of Cast-in-Place Tunnel Linings (NEWTUN).

Abstract

This user's guide describes and gives instructions for using the computer program NEWTUN. The purpose of NEWTUN is to analyze tunnels with continuous cross section. NEWTUN is a revision of an existing general-purpose program called EFFRAM which analyzes plane frame structures on elastic foundations. This interactive computer program uses the stiffness method of structural analysis and the theory of beam elements on an elastic foundation.
