In addition, being based on above method step, the embodiment of the present invention develops corresponding program, so as to more quick, smooth
Execution relevant calculation
Seismic response analysis side will be built to consideration place-urban effect region by way of specific embodiment below
Method is further elaborated.
By taking Tsing-Hua University campus as an example, the building attribute information of 619 buildings in this area is obtained by on-site inspection, including
Structure type, height, the number of plies, construction age, floor area etc., data are full and accurate.Pass through Tsinghua University archives and correlation simultaneously
Data, the place data in place where obtaining Tsing-Hua University campus, including landform, the density of every layer soil body, depth, quality factor,
Shear wave velocity and compression velocity of wave.Analysis model used in the present invention can be used to entire Tsing-Hua University campus institute using above-mentioned data
Place and its in each building simulated.Wherein, the shear wave velocity in place and transmission function respectively such as Fig. 4 (a) and
Shown in Fig. 4 (b).
When analysis, 8.0 grades of three rivers-Pinggu earthquake that place superficial objects earthquake motion China Seismology Bureau calculates is in Tsing-Hua University
Earthquake motion within the scope of ground is as a result, such as Fig. 5 (a).The earthquake centre of the earthquake and Tsinghua University's distance are about 50km, and pass through inverting
Bottom input earthquake motion (such as Fig. 5 (b)) within the scope of place is calculated, and is used for the earthquake disaster simulation in Tsing-Hua University campus.
The considerations of building essential information and earthquake motion information based on area above, proposed using embodiment of the present invention place-
The region building seismic response analysis method of urban effect has carried out earthquake disaster simulation to Tsing-Hua University campus, and directly adopts with traditional
It is compared with free survey stations acceleration Method of Seismic Disaster Analysisof result as input.Fig. 6 gives in the case place and builds
It builds dynamic respond cloud atlas (Fig. 6 (a)) and final moment in geological process 11.4s and builds collapse state situation (Fig. 6
(b)).After Fig. 7 gives the method consideration place-urban effect proposed using the embodiment of the present invention, every building peak value vertex
Number proportion (Fig. 7 (b)) is built in the growth rate (Fig. 7 (a)) of displacement and each variation range.
Further analysis shows, after considering place-urban effect, building peak value top displacement can averagely reduce 6.59%.
Wherein, the maximum range of decrease is up to 45.72%, and maximum amplification is more than 50%.But, amplification be more than 50% belong to the age compared with
Early non-masonry of setting up defences.This part building aseismicity bearing capacity and ductility are generally lower, therefore the minor change of input earthquake is
It may cause being significantly increased for building response.
For example, No. 559 3 floor are not set up defences shown in skeleton line such as Fig. 8 (a) of the first floor of masonry, the position where the building,
Ground motion response spectrum comparison in two cases is as shown in Fig. 8 (b), first floor relative storey displacement of the building in two examples
Angle comparison is as shown in Fig. 8 (c), it can thus be seen that the difference of ground motion response spectrum in Fig. 8 (c) much smaller than building in Fig. 8 (b)
Build the difference of response.This is because interlaminar shear-displacement relation of building comes under skeleton line in about 10s
Section (skeleton line peak value story drift is 0.0013) drops.At this point, the small amplification of the earthquake motion of input will lead to the structure first floor
Collapse, so as to cause the substantially change of story drift.
From the point of view of the distribution situation provided from Fig. 7 (a), the rule ten of building response variation as caused by place-urban effect
Divide complexity, has with specific input earthquake, place characteristic, building distribution situation and the mechanical characteristic for building itself
It closes.In present case, although it is contemplated that the response largely built after place-urban effect reduces, but those should not be ignored therefore
And built by the minority of more serious destruction, it otherwise may cause serious casualties.Therefore, region earthquake is being carried out
When analysis, need to pay attention to the influence of place-urban effect.
To sum up, by the above example, the considerations of embodiment of the present invention proposes place-urban effect region can be summed up
Building seismic response analysis method can get the ground motion of each site, the earthquake state of each each floor of building and position
The significant datas such as shifting, acceleration.The embodiment of the present invention can fully consider the interaction between building and the soil body, so that with
