AR 3234 - CM1 - Quiz No. 1

This design method includes both the material and load uncertainties into a single factor of safety. The calculated elastic stress in the material must not exceed the allowable stress for each of various load combinations.

(a)  

It produces lateral loadings on a structure through the structure’s interaction with the ground. Its magnitude load depends on the amount and type of ground accelerations and the mass and stiffness of the structure.

(a)  

These types of loads consist of the weights of the various structural members and the weights of any objects that are permanently attached to the structure.

(a)  

These types of structure are often used in buildings and are composed of beams and columns that are either pin or fixed-connected.

(a)  

A slab or deck that is supported such that it delivers its load to the supporting members in one direction is often referred to as a (a)   .

When all the forces on a stable structure can be determined strictly from equilibrium equations, the determinacy of such structure is (a)   .

The joint connections of a truss are usually formed by bolting or welding the ends of the members to a common plate, called a (a)   .

This type of truss is formed by connecting two or more simple trusses together.

(a)  

TRUE OR FALSE. If a truss is in equilibrium, then each of its joints must also be in equilibrium. Hence, the method of joints consists of satisfying the equilibrium conditions ΣFx = 0 and ΣFy = 0 for the forces exerted on the pin at each joint of the truss.

(a)  

The method of (a)   consists of passing an imaginary section through the truss, thus cutting it into two parts.
