Residual displacement is an important measure of post-earthquake functionality of engineering structures.
Introduction Residual displacement is an important measure of post-earthquake functionality of engineering structures after an earthquake.
Since the structure’s displacement ductility capacity is usually not known during the evaluation of existing engineering structures, prediction of residual displacement of SDOF system with constant-strength from its peak inelastic displacement is more desirable for incorporation of performance-based seismic assessment methodologies [4].
However, the evaluation of residual deformation demand plays an important role in determination the technical or economical feasibility of repairing the damaged engineering structures [4].

Comparative Study of the Housing Security Object Definition Methods Changming Hu 1, a, Jianhua Yang 1,b and Binqi Guo 2,c 1 College of Civil Engineering, Xi'an University of Architecture & Technology, Xi'an, Shaanxi, 710055, China 2 Housing security office, Xi'an Housing Administration, Xi'an, Shaanxi, 710002, China a hu.tm@163.com, b yjh3787@163.com, c 851270290 @qq.com Keywords: Housing Security Object Definition, Income Distribution, Kernel Density Estimation, Quantile Function.
From the "basic living cost" view, especially for the measure and division of the lowest-income families living income standard housing security, the civil and housing management (ie, housing security supervisor) department has feasible approach and experience.
(1) Correct understanding and definition of the housing security and the income line The income line of housing security is different from not only the low income and low income cut-off set by the civil affairs departments, but also the low-income standard published by the statistical departments.
Therefore, the income of the security object should be above the corresponding income level the civil affairs departments mean and the housing difficulty should also be considered

The sum of EECT and TECT can also be defined as the Primary Energy Cost of civil works in construction (PEC) [17].
The Transport Energy Rates (TER) are used to estimate the Transport Energy Cost (TEC) of the listed items of civil works in the building estimate of any project.
Therefore, for a given project / building: TECT = TEC1+ TEC2 +TEC3+ TEC4 +TEC5 (Eq.4) where, TEC1 = EEC of masonry work TEC2 = EEC of concrete work TEC3 = EEC of Reinforced Concrete Work (RCC) work TEC4 = EEC of flooring work TEC5 = EEC of finishing work The energy values obtained can be termed as Embodied Energy Rates (EER) of different items of civil works.
In order to compute EECT and TECT, the Schedule of Energy Rates of civil works may be worked out.
