Types of beams and loads

Cracks on a concrete slab can occur due to various reasons. Here are some common causes: 1. Shrinkage: Concrete shrinks as it cures, leading to cracks. 2. Settlement: Soil settlement or uneven foundation can cause cracks. 3. Thermal expansion: Concrete expands and contracts with temperature changes, causing cracks. 4. Poor construction: Inadequate preparation, mixing, or finishing can lead to cracks. 5. Weak subbase: A weak or unstable subbase can cause cracks. 6. Overloading: Excessive weight or pressure can cause cracks. 7. Weathering: Exposure to weather, especially freeze-thaw cycles, can cause cracks. 8. Chemical damage: Exposure to chemicals, like salt or acid, can damage concrete. 9. Poor drainage: Water accumulation can cause erosion and cracks. 10. Soil movement: Soil movement or erosion beneath the slab can cause cracks. 11. Tree roots: Tree roots growing beneath the slab can cause cracks. 12. Poor curing: Inadequate curing can lead to weak concrete and cracks. It's important to address the underlying cause to prevent further damage and ensure effective repair

In buckling, when we have a bi-articulated column, we deal with the so-called ideal buckling. ?? In this case, we use a formula without adjustment coefficients for the physical behavior of the column under study. And when we don't have this pair of links? What do we do? We use a special coefficient to adapt the mathematical result to what happens in reality considering a different configuration of the links. And how much is this coefficient worth? Well, it depends on which link we have at each end of the column and can receive the values that I put in this didactic table that I made for you! Via: @engmatheusborges/ig

Hand Calculation of “Deflection &Max.Deflection for cantilevered beam”#zaw_engineering(Solidworks)

Simply supported beam with overhang. A simply supported beam with an overhang is a type of beam that has supports at two points, with one or both ends extending beyond these supports. These beams have a span between the supports, but part of the beam extends past one or both supports without any additional support (the overhang).

Simply supported beam with linearly varying distributed load (triangular)
