This paper summarized the status of materials procurement by using information technology in do-mestic and foreign construction enterprises, and proposed to set up the procurement platform based on the informa-tion level of the construction enterprises. Further more, the platform's capabilities, as well as the integration with ERP for construction enterprises have been discussed. This paper brings forward a way for construction enterprises to reduce procurement costs and enhance competitiveness by using information technology.

Single element mesh shape evaluate index of ANSYS and SAP2000 is analyzed and summarized in the present paper.Based on this indexes, a new index is proposed. Benefit from the new index, not only single element mesh but also mesh compose of more elements can be evaluated. A cantilever beam problem is meshed by different shape and procedure programmed by C++ language is used to calculate this index of the mesh, after compared the solution with exact one, a conclusion can be draw that there is a strong correlation between the index value and the precision of solution. Multilayer and high-rise buildings mesh is also evaluated, the results show the index is still efficient and reliable.

As the resources of university laboratory is limited, the paper focuses on research of virtual laboratory for civil engineering education in China. It proposes a framework of virtual laboratory software system for civil engineering, including its deployment ideas, network deployment model and curriculum framework for virtual experiments. The virtual laboratory software system is also introduced in the article. Development and application of some typical virtual laboratory courses are given dentally, including building cognitive course, virtual experiment course in construction management, a series of training courses for whole-life building software called PKPM. The virtual laboratory software system has been applied in dozens of Chinese universities, and it provides a new reference for experiment education in civil engineering.

When reinforcing bars for concrete beam according to positive and negative moments, generally, the top and bottom longitudinal reinforcement are determined only by the most adverse effects of the positive and negative moments and the influence of compressive reinforcement is ignored in this calculation, because of not knowing the area of reinforcement which may be used as compressive bar. According to the analysis of this paper, when the reinforcement ratio is high, if not considering the beneficial effects of compressive reinforcement, the waste of materials will be caused. This paper presents a reinforcement design method which can reasonably consider the influence of compressive bar by simple comparison of moments, when not knowing the area of compressive reinforcement. This analysis can concluded that the results by the method in the paper can really achieve the purpose of saving material.
