Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis of reinforced concrete structures. Frame Analysis Software RSTAB. In this article, we are going to discuss types of beam construction and RCC design of simply supportedreinforced beam. Simply supported RCC beam construction is of.

Part of this investment has included improving the reinforcement detailing and shop drawing tools in.

Autodesk believes that Revit is better suited to meet the range of our global customer needs.

RCC Beams RCC beams are cast in cement concrete reinforced with steel bars. Beams resist compression and tensile forces and add rigidity to the structure. Beams generally carry vertical gravitational forces but can also be used to carry horizontal loads (i.e., loads due to an earthquake or wind).

The loads carried by a beam are transferred to columns, walls, or girders, which then transfer the force to adjacent structural compression members. In light frame construction the joists rest on the beam. Doubly Reinforced Beam In this article, we are going to discuss types of beam construction and RCC design of simply supportedreinforced beam. Simply supported RCC beam construction is of two types: • Singly reinforced beam • Doubly reinforced beam Singly reinforced beam A singly reinforced beam is a beam provided with longitudinal reinforcement in the tension zone only.

Compressive forces are handled by the concrete in the beam. Doubly reinforced beam • Beams reinforced with steel in compression and tension zones are called doubly reinforced beams. This type of beam will be found necessary when due to head room consideration or architectural consideration the depth of the beam is restricted. • The beam with its limited depth, if reinforced on the tension side only, may not have enough moment of resistance, to resist the bending moment. • By increasing the quantity of steel in the tension zone, the moment of resistance cannot be increased indefinitely. Usually, the moment of resistance can be increased by not more than 25% over the balanced moment of resistance, by making the beam over-reinforced on the tension side.

• Hence, in order to further increase the moment of resistance of a beam section of unlimited dimensions, a doubly reinforced beam is provided. Besides, this doubly reinforced beam is also used in the following circumstances: • The external live loads may alternate i.e. May occur on either face of the member. For example: • A pile may be lifted in such a manner that the tension and compression zones may alternate. • The loading may be eccentric and the eccentricity of the load may change from one side of the axis to another side.

• The member may be subjected to a shock or impact or accidental lateral thrust. Design procedure for doubly reinforced beam Step 1 Determine the limiting moment of resistance for the given c/s(Mulim) using the equation for singly reinforced beam M ulim = 0.87.f y.A st1.d [1 – 0.42X umax] Or Balanced section A st1 = (0.36.f ck.b.X umax)/(0.87fy) Step 2 If factored moment M u >M ulim, then doubly reinforced beam is required to be designed for additional moment. M u – M ulim = f sc.A sc (d – d’) [f sc value from page no. 70] Step 3 Additional area of tension steel Ast 2 Ast 2 =Asc.fsc/0.87fy Step 4 Total tension steel Ast, Ast = Ast 1 + Ast 2. Dear Sir/ Madam, With reference to the subject “RESIDUAL STRENGTH OF CORROSION DAMAGED CONCRETE STRUCTURES” Where can I able to get M30 grade concrete compressive strength test for corrosion damage.

For example, an experiment which someone might have carried out for a particular type of beam section. The first set of specimens shows results for what is the strength initially (uncorroded). The second set of specimen shows what is its strength after some corrosion. The next set of specimen shows strength for totally depleted concrete cover. The final set specimens show results on section strength based on reduced bar diameter.
