Calculation notebook for tension design of tie plate
the diagram shows how to use lapping zone in beams
The lapping zone for beam reinforcement bars varies: Top bars: Place at mid-span where tension is minimal. Bottom bars: Place near the ends, about 1/4 of the beam's length from the column face, where tension is lower compared to mid-span.

Crank bars
What Are Crank Bars? Crank bars are rebar sections that are bent at an angle, typically at points where the internal bending moments and shear forces are highest, such as over supports in beams and slabs. The bent-up shape helps to provide additional resistance against these forces.

Bubble Deck is concrete slab system
Bubble Deck is an innovative concrete slab system that incorporates plastic bubbles to reduce the volume of concrete used, thereby decreasing the slab's weight while maintaining its structural integrity. This method is used in construction for its efficiency, sustainability,...

Concrete
✅️The prestressing steel is high-strength steel strand that features high tensile strength and excellent toughness (tenacity of the material). ✅️Standard concrete is resistant to compressive forces but weak in tensile strength. A very effective solution to this problem is prestressing steel strand, which has five to seven times higher strength than reinforcing steel. ✅️Prestressed concrete is currently used in the construction of most long concrete bridges. In prestressed concrete structures, a tensile force is applied to prestressing steel strand with a hydraulic jack and the compressive force is transmitted to the concrete to inhibit cracks and maintain the strength and soundness of the structures
