Eriksson Pipe is a computer program that performs structural analysis and design of circular and horizontal elliptical reinforced concrete pipe. Internal dimensions of pipe culverts are sized based on hydraulic or other service requirements and are then structurally designed to support the weight of earth, live, or other loads that are imposed on them. A large number of references are available for the hydraulic design of pipe. Eriksson Pipe provides the structural analysis and reinforcing design. This computerized method of design allows the user. to obtain reinforcing steel areas for user specified pipe geometry, material properties; and loading data. ·
Eriksson Pipe completes the structural analysis and design of pipe sections by the following steps:
Compute loads on the structure.
Apply the calculated load to the structure through an assumed pressure distribution.
Complete a structural analysis.
Design reinforcing to carry the resulting moments thrusts and shears.
Other structural analysis programs are available that model the structure and the soil using the finite element technique; however, these programs offer a level of sophistication that is not required for the typical design situation and, while some finite element programs are being written for microcomputers, they require considerable computer time to process.
Eriksson Pipe is intended to be a design tool for the practicing engineer. For routine designs the engineer may input as little information as the diameter, wall thickness, depth of fill, and method of load application and then utilize a default file to generate the remainder of the input. For non-standard designs the engineer can override the default input parameter and use all the input menus to address the special conditions of his project. The . user may quickly evaluate the effects of varying any of the input parameters to select the optimum design for a particular set of conditions. Because of its flexibility, Eriksson Pipe is intended for use by engineers. Many of the input values require knowledge of design specifications with which the user must be familiar. Eriksson Pipe emphasizes this by printing the following warning with all output files:
The application of this proprietary software is the responsibility of the user. The user must select input values suitable to his specific installation. The use of default parameters does not assure a safe design ·for all installations. The information presented in the computer output is for review, interpretation, application and approval by a qualified engineer who must assume full responsibility for verifying that said output is appropriate and correct.
