Reinforced Concrete Columns
A column is a very important component in a structure. It is like the legs on which a structure stands. It is designed to resist axial and lateral forces and transfer them safely to the footings in the ground.
You can manually calculate the superimposed loads on a column in a structure using a simple process outlined in this linked article.

Columns support floors in a structure. Slabs and beams transfer the stresses to the columns. So, it is important to design strong columns.
A column is defined as a compression member, the effective length of which exceeds three times the least lateral dimension. Compression members whose lengths do not exceed three times the least lateral dimension, may be made of plain concrete.
The axial load carrying capacity of a column is deduced from the formula
Please see the link for formulas to calculate axial loads in columns. I would recommend using advanced structural design software like ETabs or Staad Pro for design of structures. Column design does not depend only on axial loads, but also on many other factors. There are bending moments and tortional forces induced due to beam spans, wind loads, seismic loads, point loads and many other factors.
In this article, we are going to discuss in detail the basis of classification of columns and different types of reinforcement required for a certain type of column.
Nguzo za Zege Iliyosimamishwa Nguzo ya Zege ni sehemu muhimu sana katika muundo. Ni kama miguu ambayo jengo linasimama juu yake. Ni iliyoundwa ili kukabiliana na axial na upande nguvu na kuhamisha yao kwa usalama kwa misingi katika ardhi. Unaweza manually kuhesabu overimposed mizigo juu ya safu katika muundo kwa kutumia mchakato rahisi ilivyoelezwa katika makala hii kushikamana. Unaweza kuniajiri kwa ajili ya mahitaji yako ya kubuni muundo. Wasiliana nami. Nguzo hutegemeza sakafu katika jengo. Vipande na mihimili huhamisha mkazo kwenye nguzo. Kwa hiyo, ni muhimu kubuni nguzo zenye nguvu. Safu ni kufafanuliwa kama mwanachama compression, ambayo urefu wa ufanisi inazidi mara tatu ya ukubwa wa chini ya upande. Compression vipande ambao urefu si zaidi ya mara tatu ya ukubwa wa chini ya upande, inaweza kuwa alifanya ya saruji wazi. axial mzigo kubeba uwezo wa nguzo ni deduced kutoka formula Tafadhali angalia kiungo kwa ajili ya formula kuhesabu axial mizigo katika nguzo. Kwa hivyo, ni muhimu kutumia programu ya ubunifu wa muundo kama vile Stackable na Stackable Pro. Ubunifu wa nguzo haitegemei tu mizigo ya axial, lakini pia kwa sababu nyingine nyingi. Kuna bending wakati na nguvu torsional induced kutokana na beam spans, upepo mizigo, seismic mizigo, pointi mizigo na sababu nyingine nyingi. Katika makala hii, tutazungumzia kwa undani msingi wa uainishaji wa nguzo na aina tofauti za kuimarisha zinazohitajika kwa aina fulani ya nguzo.
