When a structure has a complete perimeter of beams or walls the user can simplify the meshing of the diaphragm by terminating at the perimeter beam center line. The structural design revolves around four major components (Photo 3), namely (i) the reinforced concrete core wall, (ii) transfer truss/steel outriggers at four levels, (iii) large composite mega-columns, and (iv) 24m primary steel girder beam forming the major structure of the external frame. heights and reduced wall to wall strutting. It must be remembered that Diaphragm walls are. Despite the challenges faced, with considerable full-face rock excavation to reach and block the assumed cavities, the bulkhead construction works were finished ahead of the schedule to the full satisfaction of the client. It can perform both geotechnical and structural design for many wall types that include soldier pile walls, sheet pile walls, and diaphragm walls with multiple sections of reinforcement. The top of this capping beam is a construction joint for the casting of the remainder of the wall around the main girders, as described previously. On the other hand, ground beams are beams provided between adjacent pile caps and they perform as compression struts or ties in an attempt to prevent lateral displacement or buckling of piles under uneven distribution of loads on pile caps.
