WebAug 24, 2024 · The spinal cord compression was administered over the fourth cervical vertebral level in rat. Rat models were divided into five subgroups according to compression stages: sham group, group A: three-day compression rat models; group B: 12-day compression rat models; group C: 20-day compression rat models; group D: … Webthe top chord remains in compression. Though engineers often configure the top and bottom chord splice similarly, half of the splices can often be economized by taking advantage of com-pression bearing. Figure 3(a) shows a splice designed to transfer compression through a bolted splice without bearing. Figure
