Regarding the issue of jointly reinforcing the area between the two holes
Thread Content
GB150.3 6.4.1 states: \"Combined reinforcement shall be employed in the cross-section of the shell passing through the center points of the two holes.\" ”May I ask: which plane is this normal cross-section? It was also mentioned that the reinforcement area between the two holes should be no less than 50% of the total reinforcement area required for the two holes. May I ask: what exactly does the reinforcement area between the two holes refer to?
It is recommended to take a closer look at the schematic diagram for hole reinforcement calculations in order to understand how B is determined
The reason for combined reinforcement is that the reinforcement areas of the two holes overlap; in other words, there is an overlapping part in B
Cross-sectional area: the line connecting the centers of the two holes, and then based on the cross-section used for reinforcement after making the openings
Cross-sectional area: the line connecting the centers of the two holes, and then based on the cross-section used for reinforcement after making the openings
Combined reinforcement and hole drainage can be considered together
Thank you, then which part is the area between those two holes?
Thank you. What about the second question?
