Working Stress

Definition

Working Stress is the maximum permissible stress used in the working stress design of a member.

Purpose

The purpose of working stress is to ensure that structural members operate within safe stress limits under normal service conditions, preventing structural failure.

Examples of Use

• Beam Design: Calculating the maximum stress a beam can safely handle.
• Column Design: Determining the safe stress levels for columns in buildings.
• Bridge Construction: Ensuring the materials used can withstand expected loads without failure.

Related Terms

• Allowable Stress: The maximum stress that materials or structures are designed to safely withstand.
• Factor of Safety: A design criterion that provides a safety margin over the maximum expected stress.
• Ultimate Stress: The maximum stress a material can withstand before failure.

Notes

Working stress design involves applying factors of safety to account for uncertainties in material properties, loading conditions, and other variables. It is crucial for maintaining the structural integrity and safety of buildings and other structures.
