What are Boundary Conditions?

Yeong-il SeoJanuary 27, 2022

OVERVIEW

Boundary conditions represent the status of connections between the structure and neighboring structures such as foundations. Boundary conditions are distinguished by nodal boundary conditions and element boundary conditions.

Nodal boundary conditions:

The constraint for the degree of freedom
Elastic boundary element (Spring support)
Elastic link element (Elastic Link)

Element boundary conditions:

Element end release
Rigid end offset distance (Beam End Offset)
Rigid link

Design Considerations during Construction

Yeong-il SeoJune 15, 2021

OVERVIEW

 

There are cases where the design must be satisfied for two or more conditions for the same structure. In general, the design needs to be performed considering the load during construction and the load in use at the same time, as shown below. In this document, I will introduce how to perform two analyses simultaneously.
