Description |
WINSTRESS calculates the increment of stresses in a linearly elastic half-space due to surface loads. The program is part of the Productivity Tools for Geotechnical Engineers suite of programs, but is also available separately. Multiple rectangular loads, including negative loads, can model irregularly loaded areas. The system also accommodates multiple circular loaded areas. Infinitely long strip loads include uniform vertical and horizontal strip loads, vertical strip loads that increase linearly across the strip, vertical strip loads that are symmetrically triangular in section across the width of the strip, unsymmetrical triangular strip loads, and embankment strip loads that rise linearly to a level value that continues across the width of the strip. Loads extending over half the surface of the half-space include a uniform load, a load rising linearly, and a terrace load that rises linearly to a level value that continues across the rest of the half-surface. In each case a small picture on the screen illustrates the configuration of the loading pattern and the meaning of the parameters defining it. The user can choose various options for stresses to be output. These include all components of stress at a point, values of individual components along a prescribed line, and others. Output can be printed or saved in an electronic file for later manipulation by a word processor. The help files include description of the mathematical background and four worked examples representing a variety of situations that arise in practice. Units can be either British, conventional metric, or SI. |
