Innovative Ways to Enhance productivity of 5-axis Machining

In today’s fast-paced manufacturing environment, improving efficiency and productivity is more important than ever. Anyone working with 5-axis CNC machining knows that it is a great technique to enhance manufacturing efficiency and output. The best 5-axis CNC would offer the …

Equations for Crack Width In Flexural Concrete Beams

There are many empirical equations have been developed for finding the maximum width of cracks. These equations were based on the statistical analysis of experimental result data. In ACI code, two expressions have been mentioned. The two expressions were developed …

If the loads are sustained for longer duration than initial deflections increased very prominently because of the two major affects i.e., creep and shrinkage. These two effects are considered as combined in most of the cases during the calculation of …

Deflections Due To Shrinkage | Calculation | Formulas | Example

Shrinkage in concrete produces a compressive stress in the longitudinal reinforcement of beams and slabs. Tensile stress crops in response to balance the compressive stress. Usually, reinforcements are not placed symmetrically to the concrete centroid. And if the same in …

Immediate Deflection In Concrete Beams | Formulas | How To Calculate

Elastic deflections are the immediate deflections that occur only once during service period. It is not a time function i.e., there is no specific time when immediate deflections come into action. Mathematically immediate deflections can be expressed as;      …

Deflection control In Concrete Beams | Methods | Serviceability

Serviceability of a flexural beam can be achieved by limiting cracking. And the limitations on cracking can be achieved by imposing certain controls on deflections of beams. Deflection control ensures serviceability. If the deflection value is very large then it …

Factors affecting crack width | Serviceability

A beam will not fail if there is a good anchorage bond between steel and concrete. In such case, the beam will not be affected even bond get damaged along the entire span. If a valuable resistance is provided against …

Cracking In Flexural Members | Serviceability

Most of the reinforced beams cracks because of a loading that are well below the service level. Restrained shrinkage becomes one of the possible reasons for cracking in members. Flexural cracking is not only because of loading but, it also …
