Step3 calculates main member residue under Blast Loads by display dynamics analysis software and vertically carries Power, carries out degree of injury assessment by MATLAB to main member, arranges lesion assessment coefficient ψ, it is contemplated that temperature under explosive load The degree impact on structural behaviour parameter, introduces temperature correction coefficient K, the span of K by test try to achieve into [0.91, 0.99], it is contemplated that structure uses the impact on structural behaviour parameter, introducing fatigue exponent L:
L = &Sigma; i = 1 N S i ( 1 - &sigma; ) + Q i &sigma; Q i N
Wherein, SiFor the remaining life of i-th main member, QiFor the design service life of i-th main member, σ For the tired factor, the span of σ is [0.1,0.3], and N represents the number of the main member having；
The computing formula of lesion assessment coefficient ψ is:
&psi; = ( 1 - P y i KP i - T 1 ) ( S M i - T 2 &times; L ) , i = 1 , .. N
Wherein, T1Expression main member for setting is in destructiveness threshold during minor injury after Blast Loads Value, T1∈ [0,0.2],For i-th main member residue vertical bearing capacity under Blast Loads, PiFor i-th master Wanting the design vertical bearing capacity of component, N represents the number of the main member having,For i-th main member in explosive load Maximum displacement under Zuo Yong, T2Expression main member for setting is in critical potential during minor injury after Blast Loads Shifting value；
If<when 0, roof structure model meets design requirement to lesion assessment coefficient ψ, if during lesion assessment coefficient ψ>=0, needs Again roof structure is designed.
This preferred embodiment carries out the degree of injury assessment under Blast Loads to the roof structure model of design, takes and comments Estimate qualified roof structure model to construct, further ensure the capability of antidetonance of roof structure after construction；Use in blast Damage degree assessment method under load action builds roof structure model, it is achieved that design the fixing quantity of structure, assessment Method is simple, improves the speed of design, and the suitability is wide；In degree of injury assessment under Blast Loads, introduce temperature Degree correction factor, adds the reliability of design, introduces fatigue exponent so that design more closer to reality situation.
Preferably, described calculating main member residue vertical bearing capacity under Blast Loads, comprise the following steps:
Step1 slowly applies vertical load toward the end face of main member, simulates the actual vertical load born of main member, Described vertical load is the 20% of the design vertical bearing capacity of main member；
Step2 applies default explosive load at the front surface of main member, and analytical calculation obtains the complete of main member Power response procedure, wherein when the speed of all nodes on main member is less than 0.1m/s, definition structure has reached static(al) Balance, stops analytical calculation；
The speed of all nodes of main member is all forced to be set to 0 by Step3, again applies to the end face of main member Vertical force, until main member collapses, obtains the vertical force-displacement curve of main member after explosive load is damaged, according to described perpendicular The residue vertical bearing capacity of main member is obtained to force-displacement curve.
This preferred embodiment adds the reliability of design, improves the safety of roofing.
Preferably, before main member is carried out degree of injury assessment, first get rid of the interference that other disturbance brings, if other The damage that building is brought by disturbance is H, introduces interference threshold G, if H > G, the most first gets rid of interference and carries out damage again and comment Estimate.
This preferred embodiment, before degree of injury is assessed, introduces interference threshold, and other disturbance is got rid of, and adds design Reliability.
Taking σ=0.3 in this application scene, desin speed improves 10% relatively, and DESIGN RELIABILITY improves 12% relatively.
Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention Matter and scope.
