2-Way(Rc) The software is intended for the design of 2-way reinforced concrete slabs subject to a dynamic blast load, and allows for easy determinations of the dynamic properties of the slab, and the response (deflection and reactions) of the actual element, and compares it to the response criteria as established by the client. Both elastic and plastic response is considered.
The determination of the dynamic properties of the r.c. element is included. The slab may be horizontal (roof) or vertical (exterior wall). Rectangular 2-way isotropic slabs (min. ratio 1:2 = short:long), different reinforcing top and bottom, and 9 different configurations of support conditions (fixity) are possible. The software uses a numerical integration method adjusted to analyse members subject to high intensity impulse load. The algorithm considers the actual delay of the rections due to shear speed. The analysis employs the actual member properties only. Transformation factors for analysis in an equivalent SDOF sytem are not necessary, as the natural period of vibration is required for input. This property is easily determined together with the bi-linear resistance data, etc.

As Rc
Ss The software is intended for the design of structural steel beams or cladding subjected to a dynamic blast load, and allows for easy determination of the resistance ( actual and bi-linear), and the natural period of vibration.

Rc The software is intended for the design of reinforced concrete beams or walls subjected to a dynamic blast load, and allows for easy determination of the resistance ( actual and bi-linear), and the natural period of vibration.

SDOF The software is intended for the design of beams and slabs subject to a dynamic blast load, and allows for easy determinations of the response (deflection and reactions) of the actual element, and compares it to the response criteria as established by the client.
The software uses a numerical integration method adjusted to analyse members subject to high intensity impulse load.
The algorithm considers the actual delay of the rections due to shear speed.
Structural steel and reinforced concrete elements may be analysed using imperial or metric units.
The analysis employs the actual member properties only.
Transformation factors for analysis in an equivalent SDOF sytem are not necessary, as the natural period of vibration is required for input. This property is easily determined together with the bi-linear resistance data, etc.

Example
SDOF2 This SDOF software determines the response of 5 linked members (slab, beams, column) to a dynamic blast load.
The reaction history from supported beams is converted into a load history (for the supporting beam) taking into account the orientation of the beam realtive to the direction of the blast load (wave). The program automatically determines the load history in 2 cases, Case A: Blast wave across the beam, or Case B: Blast wave along the beam. The automatically created load files are hidden.
A full analysis consists of about 200 output pages of documentation.
SDOF2 shall allow you to perform Blast Design in days rather than months! For any fixed fee project this tool will make you a lot of money!
You may quickly rerun the same analysis for the same blast load facing another exterior wall by simply changing 1 input per member (Case A <-> Case B).

VCE The software is intended for the design of buildings subjected to a dynamic blast load from a vapour cloud explosion (VCE), and allows for easy determination of all necessary data for the dynamic design or analysis of the building. Side-on and reflected pressures, blast wind ("dynamic" pressure), durations, shock front velocity, etc. Explosions amplified due to reflection from "hard" surfaces. Peak overpressure vs. separation distance.
It is an extremely powerful tool for anyone involved with safety in manufacturing plants where VCE is possible.
Based upon "Predicting Blast Effects from Fast Flames", Wilfred Baker Engineering, Inc., 1998. Includes a useful chart of positive overpressure and impulse vs. separation distance.

Example
TNT The software is intended for the design of buildings subjected to a dynamic blast load using equivalent TNT charge, and allows for easy determination of all necessary data for the dynamic design or analysis of the building. Side-on and reflected pressures, blast wind ("dynamic" pressure), durations, shock front velocity, etc. Spherical and Hemispherical explosions. Reflected pressure history. Peak overpressure vs separation distance graph.
Idealized (linear) blast load is compared to theoretical (curve) blast load history, for verification of data.
Based upon the US ARMY manual T-5 1300, and "Design of Blast Resistant Buildings in Petrochemical Facilities", ASCE,1997, and "Structural Design for Dynamic Loads" by Norris et al.

Example
Leakage Pressure The software determines the internal pressure history of a hermetically sealed compartment of a building subject to a blast load, due to openings in the building envelope, based upon the US ARMY manual T-5 1300.
