In this paper we present the key factors for vulnerability modeling of historical buildings caused by dynamic loading.
These factors are: 1.
Likewise, buildings located close to major transportation routes or industrial properties, such as nuclear power plants or hazardous petroleum/chemical plants, are vulnerable if a major accident were to occur there. 3.
All offer different challenges based on factors specific to their occupancy.
Dynamic properties have a major role on the seismic behavior and vulnerability of building structures.

Though laser power has been known as a major factor affecting these responses, the detailed investigations of this factor on cut geometries and surface quality have still been deficiency.
However, the laser cutting performance for silicon can be varied by many factors, needing an insight investigation and process optimization for each particular case.
Laser power is the major parameters directly affecting the heat input during the laser cutting process.
The properties of silicon are given in Table 1.
Properties of monocrystalline silicon.

These differences result in the creation of a non-homogeneous macrostructure with different thermo-mechanical properties all the time.
The above power-law assumption is based on a simple rule about how to get the best properties from a mixture of ceramic and metal.
In terms of the impact of varied heat loads and porosity on axial stresses, Figure 5 enables them to underline the importance of these factors.
The power law type of gradation of properties across thickness has been studied, and homogeneous isotropic plates have been compared.

Utilization of non-fortified polymers as structure materials is constrained by low level of their mechanical properties, specifically quality, modulus, and effect safety.
It is clear from the results of ANOVA that the feed rate is the dominant factor affecting surface finish Ra.
Fig. 5 presents the influence of two factors on surface roughness, (i.e.
It can be seen that the CNSL% is the most important factor affecting surface finish Rt.

The following properties have great influence on the properties of asphalt pavements: mineral composition, surface properties, macrostructure, microstructure, amount of grains, volume fraction.
These factors predict the differences in specific surface areas between dolomite fractions.
High calcian particles carry the properties of calcite in limestone filler.
The tested mineral fillers have hydrophobic properties, which are favourable in asphalt mixtures.

All of the other effective factors for fabrication of nanocomposite coatings have been fixed for better studying the effect of the ASNP.
However some properties were not studied in details.
These reports are mainly discussed about the changing of average size of particles from several microns to several nanometers which is not expected to be affected from specific properties of nanometric particles.

It is, therefore, a critical issue to identify the failure mechanism and evaluate the strength properties of brazed joints.
The base and brazing materials are C1220-OL and BCuP-6, respectively and their properties are already reported in previous study [3].
It is, therefore, reasonable to infer the failure of brazed joints is caused by not only the internal flaws but also other factors.
For understanding the strength behavior of brazed joints with these factors, three dimensional finite element analysis is performed.

Mechanical properties of welds are determined by chemical composition, cooling rate (technological parameters such as voltage and current) and microstructure.
The most important factor determining the weld metal properties is chemical composition [8], and the thermal history (cycles) due to the welding processes [5].
