Stress and Strain Relationships on Stress Ribbon Structures
A bridge is a type of transportation infrastructure that is built to join two separate points of land together. Bridges often undergo construction in order to provide passage over certain obstacles such as bodies of water or geographical depressions. They can be classified in several different ways including by their intended use or by the materials used to make them. A bridge built solely for people to cross over is classified as a pedestrian bridge. Likewise, a bridge made out of wood would be classified as a wooden bridge, while a bridge made out of concrete would be classified as a concrete bridge. However, the most efficient way to classify bridges is according to their structural form (“Bridges,” 2008).
The three most basic types of bridge structures are girder bridges, arch bridges, and suspension bridges (“Bridge Technology,” 2007). The girder structure consists of a chain of beams that are interconnected and supported vertically through the use of well allocated piers. The arch structure utilizes curved elements to disperse the applied forces downwards into end abutments. Finally, the suspension structure exploits the superior tensile strength of steel cables in order to help carry the massive loads applied to the bridge. While some bridges are built basic in structure, others are made through a combination of the structural forms mentioned above (“Bridges,” 2008).
Stress Ribbon Bridge
A stress ribbon bridge is a unique type of bridge structure that is characterized by its simple catenary shape and slender concrete deck. “The stress ribbon concept borrows the suspension bridge principle but develops it further by using high-strength materials and m...

Role Strain in the Nursing Profession Essay

- As health care in America continues to undergo rampant changes, nurses are presented with the task of accomplishing much more than the traditional roles of caring for patients. These challenges are increasing the incidence of role strain within the nursing profession. Role strain, according to V. Lambert and Lambert (2001), has been intellectualized as the result of incongruences in the expectations of a particular role compared to what is actually being accomplished in the role. Understanding the influence of role strain on nurses is integral to the preservation of the profession (Lambert, V., & Lambert, 2001)....   [tags: role strain in nursing students]

Strain Theories of Criminal Behaviour Essay

- Strain theories of criminal behaviour have been amongst the most important and influential in the field of criminology. Taking a societal approach, strain theories have sought to explain deficiencies in social structure that lead individuals to commit crime (Williams and McShane 2010). Strain theories operate under the premise that there is a societal consensus of values, beliefs, and goals with legitimate methods for achieving success. When individuals are denied access to legitimate methods for achieving success, the result is anomie or social strain....   [tags: Strain Theories of Crime]

Not everyone deals with the same level of stress and there are several factors that can impact our lives and cause us to have higher or lower stress levels.

Social Structures Essay

- In the late 1730s two apprentices tortured and killed many cats as a joke and act of rebellion against their master.

Occupational Stress Essay

- Job stress has proven to be a difficult issue to tackle. Unlike physical or chemical hazards, there is not an obvious tangible hazardous agent. This issue has also been preempted by corporate stress management, health promotion, or employee assistance programs, which explain stress as a purely personal reaction, and often treat the symptoms, not the causes, of job stress. The occupational stress field also has been plagued by a variety of definitions and difficulties in measurement of stress.(Buunk,De-Jong,Y-Bemas&De wolff,1998) In addition, changes in job design or work organization are often inherently more "systems challenging" and require more radical restructuring of workplaces than red...   [tags: Work Related Stress, Job Stress]
