The concept of a "clear height" limitation on live loads is logical, but it may not be universally recognized. The American Society of Civil Engineers (ASCE) requires that the minimum live load in the design should always exceed the maximum anticipated live load during the life span of the building in the Caseloads. In addition to the aforementioned single-truck loading, which must be placed to produce the most unfavorable eect on the member being designed, AASHTO specifies that a lane loading, consisting of a uniformly distributed load combined with a single concentrated load, be considered. Suite 200, In reality, these loads do not typically take the form of uniform loads. At Structville, we stop at nothing in giving you new dimensions to the profession of civil engineering. Wind loads depends upon the velocity of wind, shape and size of the building. For a comprehensive list of live loads for various types of buildings and for provisions regarding roof live loads, concentrated loads, and reduction in live loads, the reader is referred to the ASCE 7 Standard.
