Equivalent Static Forces for Seismic Design
The UBC offers two methods for determining and distributing seismic design loads. One is the dynamic method, which is required to […]
Structural Steel
Erection Equipment
Steel buildings and bridges are generally erected with cranes, derricks, or specialized units. Mobile cranes include crawler cranes, rubber tired
Erection Procedure for Bridges
Bridges are erected by a variety of methods. The choice of method in a particular case is influenced by type of
Erection of Arch Bridges
Erection conditions vary so widely that it is not possible to cover many in a way that is generally applicable to
Equations of Equilibrium
When a body is in static equilibrium, no translation or rotation occurs in any direction (neglecting cases of constant velocity). Since
Elimination of Expansion Joints in Highway Bridges
At expansion bearings and at other points where necessary, expansion joints should be installed in the floor system to permit it

Elastic Flexural Buckling of Columns
A member subjected to pure compression, such as a column, can fail under axial load in either of two modes. One
Elastic Lateral Buckling of Beams
Bending of the beam shown in Fig. 3.90a produces compressive stresses within the upper portion of the beam cross section and
Elastic Flexural Buckling of Frames
In Arts. 3.41 and 3.42, elastic instabilities of isolated columns and beams are discussed. Most structural members, however, are part
