|
| 27. | It was built of stone arches instead of lattice girders, as many railway bridges were at the time, to avoid contemporary criticism.
|
| 28. | As with lattice girders, laced struts and ties have generally been supplanted by hollow box sections, which are more economic with modern technology.
|
| 29. | Such a member is better described as a " laced strut ", and such members frequently form a significant part of a lattice girder.
|
| 30. | His recommendation therefore like Liddell to the board of the BRC was for steel lattice girders spans, set atop brick-built supporting columns.
