Objective Question & Answer

Due to axial compressive force, the shear strength of a concrete beam is increased by a

factor:

अक्षीय संपीडन बल (Axial Compressive Force) के कारण कंक्रीट बीम की अपरूपण सामर्थ्य (Shear

Strength)

निम्नलिखित गुणांक से बढ़ जाती है:

Where:

P = Axial compressive force

Ag = Gross cross-sectional area

f_ck = Characteristic compressive strength of concrete

The axial compressive force reduces the formation of diagonal tension cracks because

thediagonal tensile stress is reduced due to the compressive stress component produced

by the axial compressive force in concrete.

Hence, the chances of diagonal tension cracks decrease when axial compression and shear

force act simultaneously.

अक्षीय संपीडन बल के कारण कंक्रीट में उत्पन्न संपीडन प्रतिबल का घटक विकर्ण तनन प्रतिबल (Diagonal

Tensile Stress)को  कम कर देता है।

इस कारण विकर्ण तनन दरारें (Diagonal Tension Cracks) बनने की संभावना कम हो जाती है।
