29. DESIGN II

The chapter discusses the design principles of frames with a focus on beam-column connections, their types (flexible, rigid, and semi-rigid), and their behavior under loads. It elaborates on the design of statically indeterminate arches, incorporating varying moments of inertia and response to temperature changes. Practical examples and calculations illustrate the processes involved in the design and analysis of structural frames.

29 Section Overview

Start current section content and materials

29.1 Frames

This section discusses the types and behaviors of connections in structural frames, emphasizing flexible, rigid, and semi-rigid joints.

29.1.1 Beam Column Connections

This section discusses the different types of beam-column connections in structural frames, including flexible, rigid, and semi-rigid connections.

29.1.2 Behavior of Simple Frames

This section discusses how simple frames behave under vertical loads, highlighting the effects of rigid connections on beam moments.

29.1.4 Design of a Statically Indeterminate Arch

This section covers the design process for a statically indeterminate, two-hinged arch rib, including loading and calculation methodologies to ensure its structural integrity.

29.1.5 Temperature Changes in an Arch

This section explores the impact of temperature changes on the structural integrity and behavior of arched structures.

Learning Objectives

  • Different types of beam-column connections include flexible, rigid, and semi-rigid joints.

  • The behavior of simple frames is influenced by how the connections reduce maximum moments under vertical loads.

  • Statically indeterminate structures often require complex calculations for analyzing load distribution and moment variation.

Key Concepts

Flexible Connection

A joint that allows rotation and can only transfer forces, leading to zero end moments.

Rigid Connection

A joint capable of transmitting moments and ensuring equal end rotations.

Statically Indeterminate Arch

An arch structure that requires additional equations to solve for forces due to the presence of more unknowns than equations.

Moment of Inertia

A property of a beam that indicates its resistance to bending, varying based on the geometry of the structure.

Temperature Effects

Changes in temperature can result in expansion or contraction of structural components, affecting stress distribution.
