This report presents the software DAD_ESWL v1.0 capable of computing efficiently the response to wind of mid- and high-rise structures consisting of up to thousands of members. The report also documents the following features of the software: (1) Use of the Database-Assisted Design (DAD) procedure or of the Equivalent Static Wind Load (ESWL) procedure for the iterative structural design of mid- and high-rise buildings. (2) Incorporation into the design of second-order elastic analysis (both P-Δ — member chord rotation, — and P-δ — member curvature). DAD_ESWL uses a geometric stiffness method allowing the second-order effects to be accounted for with no iterations. (3) Improvements in the graphical user interface, including: (i) definition of pressure tap locations, (ii) pressure distribution displays, (iii) calculation of floor wind loads due to pressures at taps, and (iv) use of MATLAB tools enabling free editing of displays of computation results. (4) Updates of steel member interaction formulas applicable to various types of beam-column joints, bracing connection details, and cross-sectional shapes. (5) Generation of biaxial interaction strength surface for determining the demand-to-capacity indexes of reinforced concrete columns or shear walls with rectangular cross section specified by the user. The demand-to-capacity index for the shear wall can be calculated as well. (6) Inclusion of the capability to use OpenSees for the efficient calculation of modal shapes and frequencies of vibration, as well as of influence coefficients. The report includes a detailed user’s manual.
