建筑 电大土木工程系 02任务_0025（The 02 task of Civil Engineering Department of architectural TV University _0025） The 02 task of Civil Engineering Department of architectural TV University _0025 What is the greatest advantage of the 1. static test? A: the greatest advantage of static testing is that all loading equipment is relatively simple, and the load is applied step by step to stop the structural deformation and give a clear concept of destruction. 2. what is heavy load? What are the advantages and disadvantages of heavy load? Answer: the so-called heavy load is the use of bulk density and easy to obtain material on the structure of the load on the method of components. Heavy load is one of the most frequently used loading methods. The advantages of heavy load are: (1) suitable for long-term construction experiment, and maintain the stability of load value; (2) load weight is easy to obtain; loading method is simple, economical and reliable. Its disadvantages are: it is time-consuming and laborious in loading process; moisture content of sand, bricks and other materials is easy to change. 3. what are the two loading methods for inertial force loading? The loading process of these two methods is briefly described. Answer: there are two kinds of loading methods for inertial load; initial displacement loading method. The initial displacement method is a method of loading a structure or member, causing it to deform, and then suddenly unloading the load to produce a free vibration of the structure or member. The initial displacement loading method is first to improve the level of potential loading apparatus, and then releasing the loading apparatus potential energy into kinetic energy, loading equipment warning a certain speed after the impact test structure, the structure of warning impact load. What is the relationship between the 4. piers and the support? What factors should be considered in selecting and designing piers? Answer: (1) pier is the supporting device of sup
