Abstract: The period of the crisis characterized by the stagnation of economy sectors has an impact especially on building activities where a large part of them is housing construction. In the field of housing, this situation has an adverse effect not only on the level of further quantitative development, but especially in the form of the suspension of the basic reproduction of housing resources that is necessary for maintaining the state of housing. The housing property management and maintenance process currently undergo greater pressure caused by budgets of the portfolio owners. The challenge of this time is to turn partially away from looking for ways of advancing and financing new housing construction and to focus primarily on optimizing the management and maintenance of the existing house and flat resources in order to maximize capacity utilization, on looking for saving, new possibilities, technologies, and tools with emphasis on the flexibility and complexity of services, and on finding ways how to set about these services as efficiently as possible for the benefit of the owners and tenants under the condition of substantial cost reductions. One of these possible tools, which is not too much known yet and is still underused in the Czech environment but which has the great potential for benefits to optimizing and improving the effectiveness of management and maintenance in the future, is BIM (Building Information Modeling).

Abstract: By collecting the China mainland liquefied survey record, analyzed the constitution of the SPT data. Have an in-depth understanding of the SPT liquefaction discrimination model in the Code of Seismic Design of Building in China. Reviews the development and evolution of the discrimination formula in the seismic code, and analyzed the results of the methods adopted in seismic codes of different versions by liquefaction survey data in mainland China, then discuss the reliability and feasibility of the current code. Eventually provide support for the amendments to the specification liquefaction method of our country.

Abstract: In the Initial impression of seismic code liquefaction conditions, when sand overburden depth is deeper than the characteristic sentenced, it will not consider the liquefied impact, in this paper use recent liquefied sites survey data to examine the liquefaction evaluations applicability. Using 1995 Kobe earthquake in Japan and 1999 Taiwan Chi-Chi earthquake liquefaction survey data, can find the characteristic depth will produce misjudgment and dangerous result; using 2011 New Zealand Ms6.3 earthquake liquefaction survey data, preliminary estimates by liquefaction characteristics depth will be make 65% of the liquefied sites misjudgment liquefaction and serious danger. Therefore, the depth of liquefaction characteristics of initial conditions for code value is not applicable, need to study to improve.
