piers must be designed accordingly, typically reinforced with vertical steel rods (rebar) and concrete fill. Anchors or straps to resist uplift are "wet-set" into the piers, secured by the concrete fill. The specification of masonry piers provides for precise placement – eliminating the need for cantilevered floor

The design of reinforced concrete structural members may be done by two different methods. One, called working stress design (WSD), is based on the straight-line distribution of compressive stress in the concrete (Fig. 1), covered in Appendix B by ACI 318. This method was the prevalent methodology up until the 1971 edition of the ACI code, and ...
Strap Footings. Stepped Footing. Combined Footings. Mat or Raft Foundation. Pile Foundation; 1.ISOLATED FOOTINGS: The isolated footing is commonly used in reinforced cement concrete columns because it very is simple and most economical as compared to the other footings. This footing is used to support a single …
σ s = V d w = 230.5 k N / m 2. The soil pressure σ s creates a bending moment in the pad foundation, and we use a cantilever beam to calculate that bending moment. Bending moment is calculated for the …
Part 5: Foundations Spread Footings Flexural Reinforcement. Requirements for the distribution of flexural reinforcement in two-way footings are given in Sections 13.3.2.2 and 13.3.3.3 of ACI 318-14, Building Code Requirements for Structural Concrete.For square footings, the reinforcement is to be distributed uniformly across the entire width of the …
The design of footings is not that simple as isolate footing. It required more calculations and attention. 4.Strap Footing with Counter Weight. The beam is provided to transfer the rotation of the footing to the …

Assumptions and Specifications for Design of Reinforced Concrete Beam 1. Beam Dimension. The size of a beam is governed by negative moments or shear forces at supports. ACI moment coefficient can be used to calculate moments of a particular span. Alternatively, designers can estimate the depth of a beam at 60 mm to 65 mm per meter …
Strap Footing Design A strap footing between two block foundations can be design in the general foundation design mode and in the plant foundation mode, for horizontal …
Supporting strap beam on interior wall; There might only sometimes be nearby or perpendicular interior columns to support the strap beam. As a result, the beam must be kept with the nearest element. …
In this article, we are going to show how the structural design of reinforced concrete pile foundations and pile caps can be done based on practical design and site experience. Design Example The frame of a 5 storey building is shown in Figure 1, and it is expected to be supported on piles with an embedment length of 20 m. The allowable …
Case 1. The grade beam is a load-bearing part of the foundation, so it has to be designed for both direct soil reaction and also any moments from the column due to lateral loads. Case 2. The grade …
This article presents a simplified analytical model for designing irregular shaped reinforced concrete (RC) footings supporting square column and subjected to eccentric loading, that is, axial load P and biaxial moments, Mx in (x-x) axis and My in (y-y) axis, respectively. In this study, four design variations of footing sections are considered, …
Comprehensive reinforced concrete beam design and detailer to all major codes of practise. This product was previously called BeamD. ... STRAP Foundation: Tool for integrating foundation design in accordance with …
Pile Foundation. The pile foundation is a type of deep foundation made of concrete, timber, or steel. It is like a small-diameter column that is driven into or cast in the ground. In simple words, a pile foundation has depth more than a shallow foundation. This foundation primly used in bridge construction.
The rebar running through the beams interlocked with the slab reinforcing and with the pier reinforcing. Once the concrete cured, the rebar in the slab and in the grade-beams created a self-supporting structure. The forms may crush over time, but the soil pressure will not be able to exert any significant force against the concrete. Grade beams.
A raft or mat foundation is a sizable concrete slab or slab-and-beam system which supports all the loads of superstructure through walls or columns in two or more rows and rests on soil layer or rock. A raft foundation may be rectangular (Fig. 1) or circular (Fig. 3). When mat foundation is supported by columns rather than the underlying ...
4. Pouring of Concrete for Grade Beam. At last, concrete is poured into the grade beam. A ready mix concrete or on-site machine-mixed concrete both can be used for concreting work. The side support of the grade beam can be 24 hours after pouring concrete. But, the bottom formwork should be removed only after concrete gains its strength.

The footing Foundation design process depends upon various structural processes. These include a soil investigation, running structural analysis of the model structure to get column reactions, design of the foundation and finally optimizing the design. Although, this is a very simplified explanation of the steps involved, it should give a good ...
The strap beam will connect the edge ftg to the mat. From RISA, the output of the moment at the area where I'm going to introduce the strap beam is 44.1 kips. ...

Concrete masonry is used to construct various foundation wall types, including full basement walls, crawlspace walls, stem walls and piers. Concrete masonry is well suited for below grade applications, because of its strength, durability, economy, and resistance to fire, insects and noise. The modular nature of concrete masonry allows floor ...
