CONNECTIONS IN
STEEL STRUCTURES
SUBJECTED TO
EARTHQUAKES

The connections are essential in conventional structures and when it comes to earthquake-resistant structures, even more so. The strength of a connection must be much higher than that of the structural member since the latter is required to be ductile.

Chapters

1.

Introduction

Essencial connections in convencional structures. Ry and Rt Values for Steel and Steel Reinforcement Materials.

2.

Structural
details

The requirements of Technical Specifications of a project – where a ductility-based design is contemplated – must be well-elaborated, adapted to the level of quality required.

3.

Brace
connections

The weakest element of the brace connections must allow the diagonal to easily reach its maximum capacity allowing rotation in the direction perpendicular to its plane.

4.

The beam-to-column
connection

The beam-to-column connection is decisive for the structure – the transfer is made by an orthogonal shear mechanism in the common rectangle.

5.

Columns
bases

In MF systems, rigidity in the bases of the columns is very important, since it influences the displacements and the buckling effective length.
