Connections

In steel structures, connections are the members that join two or more steel members. The connections are the most important members of any steel structure, and hence, they are designed more carefully. The majority of the construction cost of steel structures is incurred due to the connections. The design of connections is done as per the recommendations and specifications of the American Institute of Steel Construction (AISC).

A preengineering baseline was run down a very steep hill (see Figure). The vertical angle is turned to a point on a plumbed range pole that is 4.88 ft above the ground. The slope distance from the theodolite to the point on the range pole is 148.61 ft. The theodolite’s optical center is 4.66 ft (the height of the instrument) above the upper baseline station at110+71.25. If the elevation of the upper station is 377.93, what is the elevation of lower station? (15) What is the chainage (stationing) of the lower station? (10) Note: The chainage is computed in the horizontal plane
