Based on the research of normal confined concrete (NCC), regional confined concrete (RCC) was proposed years ago by authors. With the introduction of regional confinement concept, different mechanical properties, failure mode and energy dispatching property developed in the regional confined concrete elements. Experimental researches have been carried out during the past years on the elements under various loads, including beams under moments, short beams under shears, short columns under axial loads, middle long columns under eccentric loads, middle long columns under axial loads and columns under cycling loads. Experimental results indicated that RCC elements are more ductile, have better load carrying capacity and larger energy dispatch capacity than that of NCC elements. Stress-strain relationship of RCC, integrated confinement factor and some computation expressions for elements under various loads are proposed. Pilot projects have been conducted and regional confined concrete structures are ready for service.

Purpose:-Customer relationship as a measurement of assets, is the object of customer relationship management (CRM).the purpose of this paper is to through measuring the total assets of customer relationship in a scientific way and provide an effective way to overall understand of customer relationship management (CRM). Approach:-From the influence factors of customer relationship assets, using the method of interpretive structural model(ISM) which is contended in system engineering, to determine the relationship among the various factors which can influence customer relationship, and finally construct a measurement index system to measure customer relationship assets(CRA). Findings:-Customer relationships can be measured as an asset, and we can find a new way which basic on interpretive structural model to quantify customer relationship assets. Originality/value:-As one kind of firms' intangible assets,customer relationship assets is very important to improve the competitiveness of enterprises, therefore how to measure and quantify customer relationship assets become very useful to customer relationship management.

In order to promote CRM strategic research and improve CRM capabilities of the theoretical basis of decision support function, based on the brief analysis of the current situation about B2B customer relationship management, discussed the practical significance of the implementation of the brand promise made in the B2B customer relationship management, and focused on the applications of the four strategies of brand promise in customer management relations in the B2B enterprise: Implementation of the "customer centric" brand promise; Strengthening the brand promise based on the quality of enterprise products and services; Playing the importance of staff; Continuing to fulfill the brand promise.
