Abstract The interaction of factor Xa with factor Va on the membrane surface results in a 3,fold increase in the kcat for the activation of prothrombin catalyzed by factor Xa. The reaction between the transition state irreversible inhibitor dansylglutamyl-glycyl-arginyl chloromethyl ketone DEGRck and factor Xa was characterized and employed to evaluate changes in the active site of factor Xa resulting from its interaction with factor Va, which may account for the increased catalytic efficiency of the enzyme complex. The incorporation of DEGRck into the active site of factor Xa results in a large change in the fluorescence intensity of the dansyl moiety. The fluorescence change was employed to study the reaction between enzyme and inhibitor directly by stopped-flow fluorescence measurements. The fluorescence traces were biphasic, indicating that the association of DEGRck with factor Xa and the subsequent covalent modification of the active site could be resolved because of differences in fluorescence intensities of the intermediate and product. This interpretation was verified by rapid chemical quench experiments.
Therefore, separate studies are recommended to study the effect of near-field earthquakes on the governing collapse mechanism and collapse fragility.

Reinforced concrete moment frame structure is most common type of construction to resist earthquake.
Beam and columns in frame structure are properly proportioned and detailed to resist flexural, axial and shearing actions produced during strong earthquake ground shaking. Various seismic design codes define these frame structures in different ductility classes with specific response reduction factor based on proportioning and detailing of structure.
All codes define procedures to estimate drift and allowable limits of drift, however difference is found due to effective stiffness of structural members. Earthquake is a global phenomenon.
Due to frequent occurrence of earthquakes it is no more considered as an act of God rather a scientific happening that needs to be investigated. During earthquake, ground motions occur both horizontally and vertically in random fashions which cause structures to vibrate and induce inertia forces in them.
Analysis of damages incurred in moment resisting RC framed structures subjected to past earthquake show that failure may be due to utilization of concrete not having sufficient resistance, soft storey, beam column joint failure for weak reinforcements or improper anchorage, column failure causing storey mechanism. Beam-column connection is considered to be one of the potentially weaker components when a structure is subjected to seismic loading. Most of the older provisions have been redrafted and modified for greater clarity and new provisions have been added.
The principle of superposition is dropped for estimating the design moment of resistance of structural walls with boundary elements and a new alternative procedure is mentioned. The software is able to predict the geometric nonlinear behavior of space frames under static or dynamic loadings, taking into account both geometric nonlinearity and material inelasticity.
