A new model that can simulate the behavior of construction joint subjected to seismic forces was proposed. Nonlinear time-history analysis was carried out for reinforced concrete regular frame structures designed in different seismic intensity regions as well as with different height-to-width ratios. Two kinds of numerical models are adopted to simulate the seismic behavior of each frame, one with construction joint using the new proposed model and the other without construction joint using the conventional model. Results show that the influence of construction joint on the seismic behavior of reinforced concrete frame is strongly related to structural nonlinearity. It may increase the top displacement and the inter-story drift, change the inter-story drift distributions, and exacerbated the local reaction of key members. The influence of construction joint cannot be ignored for structures with low emergency capacity against major earthquake. Seismic design suggestions are proposed from the aspect of calculation analysis method.

Reinforced Concrete Frame Structure

To investigate the effect of the horizontal construction joint on seismic behavior of the exterior joint of the reinforced concrete frame structure, the numerical simulation of the exterior joint with the construction joint under the low cyclic loading was done. The experimental results and the numerical simulation values were compared. Seen from the ultimate load, the experiment value is 158.7kN, the simulation value is 170kN, the relative error is about 11%.Further analysis of the exterior joint of reinforced concrete frame skeleton properties, the feasibility of applying unit construction joints is verified.
