Because of the Complication in dynamic experiment of concrete, stiffness and accuracy of test equipment are required strictly. And there are different experimental methods in tests, conclusions are different in different tests. According to the test of dynamic properties for concrete, the research status about the equipment for uniaxial tensile and compressive strength of concrete was discussed in...
Thorough summarizing the earthquake damage of the towns and villages housing, and the reason why the traditional ring beam and constructional column are difficult to implement in town buildings, the seismic techniques of fabricated constructional column and ring beam was proposed for different intensity area. The ring beams and constructional columns are characterized by the special lining made of...
The capability of structure resisting progressive collapse depends on controlling the dispersion of damage by uncommon agency in the part of the structure and to avoid the destruction just likes the Domino action. For the RC frame, when one column under the beams is broken, the key to avoid progressive collapse is whether the frame beams can bear the column's load to produce a new way for transmitting...
For resolving the difficulty that slab-column system can not be popularized in high-intensity earthquake area, a new-type concrete filled steel tubular column-slab joint is presented in this paper. The new-type joint is characterized by forming a hinge joint between the steel tubular column and the concrete flat in interior of building. And it has no use for horizontal loads, which bore completely...
