A circular highway curve has the following design elements: • 1 = 65°32'17" • D= 3°52'00" • Pl station = 36 + 45.00 • Pl coordinates: N = 10,000.00 ft. E = 15,000.00 ft. · Bearing of the radial line from the BC to the center of the circle: S 32°46'08" E • This is a typical curve. The BC is on the left, stations increase to the right, and the radial lines ar perpendicular to the tangents.

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).
