ZERO21 Interview Questions and Answers

Soil Bearing Capacity (S.B.C.) is the maximum pressure that can be applied to the soil without causing shear failure.

• S.B.C. is a crucial factor in determining the foundation design of structures.

• It is influenced by factors such as soil type, moisture content, and compaction.

• The S.B.C. is usually expressed in units of force per unit area, such as kN/m^2 or psi.

• It is important to conduct soil tests to determine the S.B.C. before construction.

• Exceeding the S.B.C. can lead to set...read more

• Cantilever beams

• Simply supported beams

• Fixed beams

Different types of foundations include shallow foundations, deep foundations, and specialized foundations.

• Shallow foundations: spread footings, mat foundations, strip footings

• Deep foundations: piles, drilled shafts, caissons

• Specialized foundations: floating foundations, pile caps, raft foundations

Designing a beam involves several steps to ensure structural integrity and safety.

• Determine the load requirements and constraints

• Select appropriate materials based on load and design specifications

• Calculate the beam dimensions and cross-sectional properties

• Analyze the beam for stress, deflection, and other structural considerations

• Iterate on the design to optimize for cost, weight, and performance

• Create detailed drawings and specifications for fabrication and construction

Construction joints are used to separate different pours of concrete, while expansion joints allow for movement due to temperature changes.

• Construction joints are used to separate different sections of concrete that are poured at different times.

• Expansion joints are designed to allow for movement in the concrete due to temperature changes, preventing cracking.

• Construction joints are typically planned and intentional, while expansion joints are necessary for the structural int...read more
