Based on the data from dynamic analysis of a 40m-span multi-box steel-concrete composite bridge and the difference value of its modal curvature before and after the structural damage, this paper detects the damage locations in steel-concrete composite bridge by modal curvature difference method (MCDM).
Here we adopt the updated finite element model in last work as analytical model, taking concrete density and elastic modulus as updating parameters and modal frequency+MAC as reference data.
For this reason, this paper bases on the data from dynamic analysis of a composite bridge and the change of its modal curvature before and after the structural damage to detect the location of damages in steel-concrete composite bridge.
Eq.(1) is solvable for successional system, but in fact data on mode shapes by practical test or finite element dispersed is a series of scatters.
In order to investigate the change in modal curvature of simply supported multi-box steel-concrete composite bridge due to local damage and the influence of concrete or steel material local damages in typical positions (mid-span or 1/4 span) of the bridge, several cases of local damage are pre-set by considering 30% elastic modulus reduction and analyzed by the FE models.

Experimental data clearly shows that the incubation time for recrystallization is increased by precipitation.
The values of L0 and D0 were identified by fitting the experimental data of [24]; L0.D0 = 1 x 10-22 m3/s.

For the interest of space, this contribution has privileged the data of [24] in which the recrystallized fraction was directly measured by optical metallography.

The procedure is then tested with experimental data collected on a wide-flange steel beam.
In their studies, measured modal test data along with a correlated analytical structural model are used to locate potentially damaged regions using residual modal force vectors and to conduct a weighted sensitivity analysis to assess the extent of mass and/or stiffness variations, where damage is characterized as a stiffness reduction.
Friswell [26] identified the location of damage from vibration data using genetic algorithm, and estimated the degree of damage in these location.

Analysis on Test Data.
Conclusions Based on the analysis on test data, we can draw the following conclusions: (1) The three kinds of samples will expand if soaked in water, as there are expandable minerals in them.

In this case, the chemistry of the process corresponds to the method of combining the density diagrams of simple substances (elements, components, phases and chemical compounds) in elucidating the mechanism of complex compound formation from simple data.
As a working hypothesis is putted the change periodicity availability of the compounds and materials internal temperature relative to the temperature rise sphere, which appears itself during the heat transferring in a series of measurements, that will systematize and simplify data processing.

The seismic record is great important data in studying the characteristics of ground motion.
Studying of the records data, to reveal the distribution of seismic energy in frequency domain, to guide the synthesis of the ground motion time history is necessary.
The data have been divided into two groups according to the size of the moment magnitude: Mw5-6.5 and Mw6.6-7.3.
Energy accumulation curve of every record data in horizontal and vertical direction within 0.1-50 Hz have been shown in figure 1 and figure 2.
From the study, the corrected time history based on energy accumulation curve is feasible when applied to simulate near-field ground motion with stochastic finite fault method, but limited by earthquake data, how to choose the amplification factor for different earthquake is still questionable.
