thick, 3 m long and is designed as braced structure with pin-connection at the floor levels. The wall is erected with a 20 mm thick horizontal joint which is to be grouted. Vertical ties from foundation to roof are provided at intervals along the wall length. a. Loading: Total statical floor area carried by the […]

The structural system shown in a typical layout in Figure 4.13 consists of cast in-situ prestressed flat plates of typically 175 mm thickness. The floor is supported by a series of precast load bearing walls which are generally 200 to 250 mm thick depending on the gravity loads the wall carries. The precast walls are […]

1. Project Description The project consists of four blocks of 30-storey residential apartments with basement carparks. There are four units on each floor which includes a common passenger lift, fire lifts and two staircases. Floor to floor height is typically at 3.2 m. For design illustration, only a typical floor structural system is presented. It […]
