Performance-Based Earthquake Engineering
What Can It Do for You?
There's been a lot of talk, and some confusion, lately about performance-based earthquake engineering (PBEE). Many geotechnical engineers wonder -- what is it, how does it differ from what I've been doing,...

Geotechnical Delivery on Mega Transportation Projects: Challenges of Accelerated Delivery
Transportation projects have traditionally been delivered through the design-bid-build (DBB) delivery model, which continues to be the preferred method of delivering the majority of smaller and more traditional...

General
Design of Latticed Steel Transmission Structures specifies requirements for the design, fabrication, and testing of members and connections for electrical transmission structures. These...

Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Design of Connections
Bolted connections for transmission structures are normally designed as bearing type connections. It is assumed that bolts connecting one member to another carry the load in the connection...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

The Hail Problem
Unlike some other forms of precipitation, hail comes in bursts of short duration, falls over isolated and unpredictable locations, and usually occupies only a small percentage of the total...

The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...
