ASDIP Structural Foundation v3.2.3 [Size: 62 MB] ... ASDIP FOUNDATION is structural engineering software utilized by engineers for design of foundations, such as spread footings, strap footings, and combined footings. ASDIP FOUNDATION substantially simplifies time-consuming calculations for structural engineering design. Spread Footing Design: This structural engineering software computes soil bearing pressures induced by a square or rectangular spread concrete footing subject to vertical load and biaxial moment. This structural engineering software analyzes stability of structures for overturning, sliding, and uplift. The software performs concrete design based upon Ultimate Strength Design Method within ACI 318. Load combinations occur per ASCE 7. Columns may be eccentric in two directions. The footing is assumed to be perfectly rigid with constant thickness and rotates about its mass center to maintain equilibrium of forces. A remarkable feature of the ASDIP FOUNDATION software is its ability to determine the soil pressures under the footing with any service load combination including uplift loading. The pressures may also be calculated when only a part of the footing is in contact with soil (partial bearing). These type software advantages are especially useful when a footing with small vertical load and big moments is designed such as a footing at the corner of a building under lateral loads. Input: The required input data includes the footing and column dimensions, materials’ properties, allowable soil bearing pressure, and acting service and factored loads. In addition, the software accepts a number of load cases, such as dead, live, snow, wind, and seismic to be combined internally. Model a single set of pre-combined loads. Output: The program checks the footing stability in overturning, sliding and uplift for the service combined loads, and performs the concrete design, which includes the one-way shear, punching shear and bending for the factored combined loads. In each case the controlling load combination is identified and reported. In case of partial bearing, the software accurately calculates the bearing pressure distribution on the base of the footing. The one-way shear, the punching shear, and the bending moments are calculated based on the bearing pressures under the factored loads. The program uses a sophisticated algorithm based on integrals to find the areas, volumes, and centroids of these irregular resulting geometric shapes. A detailed step-by-step report is available to the touch of a tab, which is updated with every new change. In addition, ASDIP Foundation uses a pre-formated colorful text-with-values output for easier identification of the problem areas. ASDIP Foundation generates a graphical view of the designed footing and the resulting pressures and forces, as shown. The program also generates the moment and the shear plan views for the controlling combination, as well as a view of the construction section and elevation with the reinforcement information.

Strap Footing Design: A strap footing is one that usually supports two columns, and therefore is a special type of combined footing. If a property line exists at or near the edge of an exterior column, an isolated footing would be placed eccentrically under this column and it would tend to tilt. Overturning of the exterior footing is prevented by connecting it with the adjacent interior footing by a strap beam. Since this beam is subjected to a constant shear and a linearly varying moment, which are the characteristics of a cantilever beam, this system is called strap footing or cantilever footing. The use of a strap footing may be justifiable under conditions where the distance between columns is large and a large excavation area must be avoided. It is common practice that the bottom surfaces of the exterior footing, the strap beam, and the interior footing be at the same elevation, but the thickness of each element may be different, depending on the strength requirements. This module computes the soil bearing pressures induced by a cantilever footing under the action of vertical loads and bending moments, per the latest ACI design criteria. It designs the reinforcing steel for the interior and exterior footings, and checks the one-way and two-way shear stresses. In addition, the program generates the shear force and bending moment diagrams in order to design the reinforcement for the strap beam. The concrete design is based on the Ultimate Strength Design Method of the ACI 318. Load combinations per the ASCE 7. Both columns may be eccentric in the longitudinal direction. INPUT: The required input data includes the footings, strap and columns dimensions, the materials’ properties, the allowable soil bearing pressure, and the acting service and factored loads. In addition, the program accepts a number of load cases, such as dead, live, snow, wind and seismic, to be combined internally. Alternatively, you can model a set of pre-combined loads. OUTPUT: This module checks the overall footing stability under the service combined loads and performs the concrete design of the two footings and the strap beam, which includes the one-way shear, punching shear and bending moments under the factored combined loads. In each case the controlling load combination is identified and reported. For a quick overview of the design results click the “At a Glance” tab. A more detailed step-by-step calculations are available at the “Detailed” tab, which is updated with every new change. In addition, ASDIP Foundation uses a pre-formated colorful text-with-values output for easier identification of the problem areas. Use the Print Preview command to see a preview of the pre-formatted report on-screen, which includes the color graphics generated by the software. ASDIP Foundation generates a graphical view of the designed footing and the resulting pressures and forces, as shown. The program also generates the moment and the shear diagrams for the controlling combination, as well as a view of the construction section and elevation with the reinforcement information.

Combined Footing Design: A combined footing is one that usually supports two columns. If a property line exists at or near the edge of an exterior column, an isolated footing would be placed eccentrically under this column and it would tend to tilt. Overturning of the exterior footing is prevented by supporting the two columns on a common footing. The use of a combined footing may be justifiable under conditions where the distance between columns is short and the stability of an exterior isolated footing would be compromised. It is common practice to size the combined footing so that the resulting soil bearing pressure is uniform. To accomplish this, the footing shape is sometimes trapezoidal or rectangular, depending on the loads. A combined footing is usually analyzed as a beam in the longitudinal direction and as a footing in the transverse direction. This module computes the soil bearing pressures induced by a cantilever footing under the action of vertical loads and bending moments, per the latest ACI design criteria. It designs the reinforcing steel, and checks the one-way and two-way shear stresses. In addition, the program generates the shear force and bending moment diagrams in order to design the reinforcement in the longitudinal direction.

ASDIP Retain v3.7.1 [Size: 61.5 MB] ... ASDIP RETAIN is structural engineering software utilized by engineers for design of retaining walls. ASDIP RETAIN is based upon the latest IBC / ACI 318 specifications. ASDIP RETAIN greatly simplifies time-consuming calculations in a structural engineering office. Cantilever Retaining Wall Design: This structural engineering software computes soil bearing pressures and analyzes stability of the structure. In addition, the stem can be either concrete or masonry. It performs concrete design based upon Ultimate Strength Design Method of ACI 318, and the masonry design per MSJC. The lateral pressures are calculated either per Rankine, Coulomb, or Equivalent Fluid theories. Seismic design based upon Mononobe-Okabe approach. Load combinations per latest IBC ASCE 7. Input Data: The input data required includes the geometry of the backfill, stem, toe, heel, and key. In addition, the program accepts a number of load cases, such as surcharge (strap, uniform and/or concentrated), wind, and seismic. The reinforcing steel may be specified and customized using multiple options. In addition, find the steel reinforcement to satisfy the strength requirements of all the controlling load combinations. Conservatively, ignore the soil bearing pressure in the heel design. Output: The program checks the wall stability for the service combined loads and performs the concrete design of the stem, toe, heel and key for the factored combined loads. In each particular case the controlling load combination is identified and reported. A detailed step-by-step report is available to the touch of a tab, which is updated with every new change. In addition, ASDIP Retain uses a pre-formated colorful text-with-values output for easier identification of the problem areas. ASDIP Retain generates a graphical view of the designed retaining wall and the resulting pressures and forces, as shown. The program also generates the moment and the shear diagrams for every load combination, as well as a view of the construction section and elevation with the reinforcement information. Note that the rebars can be easily optimized this way.

Restrained Retaining Wall Design: Retaining structures hold back soil or other loose material where an abrupt change in ground elevation occurs. The retained material or backfill exerts a push on the structure and thus tends to overturn or slide it, or both. Sometimes movement of the wall is restrained at the top, as in a basement. In such a wall, the overturning is prevented. The stem acts as a fix-pin beam and the heel and toe of such a wall act as cantilever beams. Since the wall cannot deflect, the backfill pressure is generally the at-rest condition rather than active condition. The design involves two major steps: the first one is the evaluation of the stability of the whole structure under the service loads, which includes the settlement and sliding failure modes, and the second one is the design of the different components, such as the stem, heel, toe and key, for bending and shear, under the combined factored loads. This structural engineering software computes soil bearing pressures and analyzes the stability of the structure. The stem can be either concrete or masonry. This software performs the concrete design based upon Ultimate Strength Design Method described within ACI 318. The lateral pressures are calculated either per At-rest, Rankine, Coulomb, or Equivalent Fluid theories. Seismic design of the backfill and water table.
