Long-Span Framing
Large industrial buildings, auditoriums, gymnasiums, theatres, hangars, and exposition buildings require much greater clear distance between supports than can be supplied by beam and column framing. When the clear distance…
The Complexity of Biomechanics
I really enjoy studying biomechanics. I find it totally fascinating to learn, for example, that a certain muscle is very well suited to stabilize a joint, but not…
Skeleton Framing
In skeleton framing all the gravity loadings of the structure, including the walls are supported by the steel framework. Such walls are termed non-bearing or curtain walls. This system made…
Structural Framing Systems
Steel construction may be classified into three board categories: wall-bearing, skeleton, and long-span framing. Depending on the needs of the building, one or more of these categories may be incorporated.…
Geosynthetics
A geosynthetic is defined as a planar product manufactured from polymeric material and typically placed in soil to form an integral part of a drainage, reinforcement, or stabilization system. Common…
Biomechanics Definition
Everyone has been to a mechanic before. Likely you took your car to him or her either for regular maintenance or because something went wrong. Because of their understanding of…
Foundation Excavations
There are many different types of excavations performed during the construction of a project. For example, soil may be excavated from the cut or borrow area and then used as…
Foundations
This section deals with the selection of the type of foundation. The selection of a particular type of foundation is often based on a number of factors, such as: 1. Adequate…
12-Lead ECG Placement Guide with Illustrations
As a non-invasive yet most valuable diagnostic tool, the 12-lead ECG records the heart's electrical activity as waveforms. When interpreted accurately, an ECG can detect and monitor a host of…
The ECG Leads, Polarity and Einthoven’s Triangle
There are three lead systems that make up the standard ECG: · Standard Limb Leads (Bipolar): I, IlI & III · Augmented Limb Leads (Unipolar): aVR, aVL & aVF · Precordial Leads: V1- V6…
