Structural Analysis
Equations of Condition for Plane Trusses
In Section 3.4, we indicated that the types of connections used to connect rigid portions of internally unstable structures provide
Erection Methods for Buildings
The determination of how to erect a building depends on many variables that must be studied by the erection engineer long
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
Equations of Equilibrium
When a body is in static equilibrium, no translation or rotation occurs in any direction (neglecting cases of constant velocity). Since
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
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
Erection of Cable-Suspended Bridges
The ease of erection of suspension bridges is a major factor in their use for long spans. Once the main cables
