The experimental teaching platform of structural mechanics in Civil Engineering College of Qinghai University was completed

In November 2020, the construction of the structural Mechanics experimental teaching platform project of Civil Engineering College of Qinghai University undertaken by our company was completed.

The Experimental Teaching Center of Basic Mechanics of Qinghai University is affiliated to the College of Civil Engineering. It is an experimental center managed by the university and the college, and also a university-level experimental center of Qinghai University. The Basic Mechanics Experimental Center, formerly known as the Mechanics Laboratory, was founded in 1985 and belongs to the Department of Construction engineering. It is a technical (professional) basic laboratory. It is one of the basic laboratories of Qinghai University, and undertakes mechanical experiment tasks for all engineering undergraduates.

Construction mechanics experiment teaching center in "mechanics of materials, theoretical mechanics, mechanics of construction, engineering mechanics, structural mechanics, elastic mechanics and finite element analysis, structural dynamics, elastic-plastic mechanics, the finite element principle and application" to represent the mechanics of high quality teaching resources, such as continuous with various links up for the engineering speciaty, and provide theoretical and technical support for engineering education.

Through the structural mechanics experiment teaching platform construction, the new structural mechanics laboratory teaching modules and functions of the basic mechanics experiment teaching center of experimental curriculum system gradually according to the economic construction and social development in the new century the need for high quality innovative talents cultivation, closely integrated with the theoretical teaching, scientifically set up the experimental project, and pay attention to advanced, open, And the scientific research results into experimental teaching, to form a systematic and scientific, complete curriculum system adapted to the characteristics of the subject and its own, comprehensive training of students' scientific style, experimental skills and comprehensive analysis, discovery and problem solving ability, so that students have innovation, entrepreneurship and practical ability.
