Can you design continuous beam as simply supported beams?
No
What is a minimum length for beam suppot on bearing wall?
That depends on what the beam is supporting above. Ideally 150mm bearing is the minimum. I have seen as little as 50mm! But any engineer would frown upon this.
What is the maximum overlap of steel rods in reinforced concrete sections?
Steel reinforcing rods have minimum overlap requirements to ensure that the reinforcing has a continuous effect throughout the structure.In some instances this minimum overlap is 600mm, but the requirement does vary and must be confirmed by an Engineer for each particular design.Maximum overlaps would be used to ensure wastage is reduced, and to ensure adequate concrete cover.
Is simply supported beam better than fixed for seismic design?
Most beams for buildings are bolted together and allow some rotation at the fittings, and are treated as simply supported beams. It is not question of better but of practical design. If rigid connections with fixed ends are desired, it will usually invove welding
What thumb rules do you follow while assigning the size of a beam in RCC design of structures?
depth of a beam can be approximately calculated as follows span/12 and breadth=depthX(1/2 to 2/3)
What purpose concealed beam used in slab design?
what pupose concealed beam use in slab design
What is the minimum anchorage length for reinforcement?
It is the length of the main bar provided at the column beam junction or column footing junction to allow for the development of stresses to its design strength.
Why does Low beam stop working while high beam indicator is on?
it;s design that way
What is the pivots job in a beam balance?
To support the weight of the mechanism, and everything added to the beam, and to provide minimum "stiction".
What is the minimum mass a triple beam balance measure?
0.01g
What is the minimum percentage of steel to be provided for a beam?
10-15%

What is the minimum compression reinforcement to be provided in singly reinforced beam?
3000 psi
Why is an I-Beam stronger in its weight than a simple rectangular beam?
The vertical portion of the I-beam resists shear force better than a rectangular one. The "I" portion also deflects force because of its design.
