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.

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.
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
That is not a simple anwer. It depends on the roof design and how many, and where the load points are, and the material of the beam(wood, metal, composite). See a structural engineer.
what pupose concealed beam use in slab design
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.
To support the weight of the mechanism, and everything added to the beam, and to provide minimum "stiction".

An overlap waistband is a design feature commonly found in certain types of clothing, such as skirts or pants, where the fabric of the waistband extends over itself, creating a layered effect. This design can enhance comfort and provide a secure fit by preventing gaps. It can also add visual interest and style to the garment. Overlap waistbands are often seen in maternity wear and activewear for added flexibility.
The overlap between rulers can vary depending on their design and intended use, but generally, it is measured by the length of the combined scales that can be aligned. For standard rulers, there is typically no significant overlap since they are used individually. However, in specific applications or designs, such as folding rulers or adjustable rulers, the overlap can be a few centimeters. In practice, ensuring proper alignment is more important than the exact overlap length.
