The main arch ring is a structure of twin separated arch ribs, connected by eight reinforced concrete floor beams. A catenary of m= 1.543 was chosen as the arch 有13 m九个spandrel间距的每个在主要间距; 13 m三个间距的每个为南方法; 15 m一个唯一间距为北部方法。 主要曲拱圆环是孪生被分离的...

The shear strength predictions of 233 simply supported deep beams, shown in Table 1, have been evaluated by the original STM and the proposed modified STM (Eq. (19)). The concrete strength of the deep beams varied from 16 to 120 MPa, including normal and high strength concrete. The beams...
Below we give a rough "rule of thumb" that will provide a reasonable guess at allowable deck joist spans for most lumber species and grades: While it is by no means a substitute for a proper table of spans and sizes of framing lumber, home inspectors often use a quick and dirty "rule...
Multiple branch beams are arranged on the supporting portion and arranged at intervals in the length directions of the main beams. According to the internal-span unsupported convenient construction support and method for the bridge cast-in-place box beam, the supporting structure is arranged on the...
Large-scale experimental and analytical seismic studies of a two-span reinforced concrete bridge system. A quarter-scale, 67 ft (20.5 m) long asymmetric reinforced concrete bridge model with two-spans supported on three, two-column piers was tested using the shake table system at the University ...
All tested beams failed due to diagonal cracking or to concrete strut failure. First visual cracking and failure load values are summarized in Table 2. During the tests, the load was periodically paused to observe cracks. The load at which cracks occurred was determined by visual inspection. Dis...
All primers are listed in Supplementary Table 2. RT–qPCR was performed using a C1000 thermal cycler (Bio-Rad). Melt curves were examined to ensure the specificity of the primers. Results were analyzed using the ΔΔCt method. For each biological replicate, the median Ct value of three ...
