ESDU 92036 introduces ESDUpacs A9236 and B9236 for the calculation of response of structures due to respectively the along-wind and across-wind components of turbulence. The first program is based on ESDU 87035 and 88019@ while the second is based on ESDU 89049. Four separate cases may be treated. The first is a uniform ground-based vertical cantilever@ and responses are deflection and acceleration at the top and bending moment at the base. The second is a uniform line-like structure that may be inclined in the cross-wind plane with its base above ground level; responses are deflection@ acceleration and bending moment at mid-span of a single-span structure@ or deflection and acceleration at the tip@ and bending moment at the base@ of a cantilever. The final cases are for non-uniform structures with mass distribution and width varying along the structure. For the non-uniform ground-based cantilever@ deflection@ acceleration@ shear force and bending moment at any height may be requested. For the non-uniform general case@ the structure may be inclined in the cross-wind plane and the base may be above ground; responses for such cantilevered structures are the same as for the uniform ground-based cantilever@ while for a single-span structure deflection and acceleration may be requested at any height with@ for fixed or pinned ends@ the shear force at the ends and the bending moment at mid-span and@ additionally@ for fixed ends only@ the bending moment at the ends. The programs are provided on disc in the software volume as source code with file input/output@ and compiled with a user-friendly front end that prompts on screen for data@ both for use under PC DOS.
