POM-NOM NEW GUINEA EMBASSY

The structural system used for this building is comprised of a two way concrete slab on a concrete rigid frames of beams – columns and concrete shear walls supported on pile foundation. The building is characterized as a dual system with sway intermediate concrete moment resisting frame system with rigid diaphragms on every story. The rigid diaphragm is a typical two way slab of 10” thick as specified on the construction documents.

The vertical and lateral main seismic and wind resisting system is formed by a the same structural system in both orthogonal direction as described below: 

Main Seismic and Wind Force Resisting System in North-South and East-West Direction:

For the north south direction, gravity loads are picked up by a concrete two way slab system supported on a moment resisting concrete comprised of columns – beams and concrete walls all throughout. According to the ASCE -7 table 12.1.2-1.E the lateral system is defined as a dual system comprise of an intermediate concrete moment resisting frame and special reinforced concrete shear walls.

The 2012 OBO ICS indicates that the NOB is an occupancy III category structure, which requires the prescriptions for Enhanced Local Resistance (ELR) and Alternate Path Method (AP) for structural member design when considering Progressive Collapse (PC). Within the AP method of design, two separate analysis approaches were employed, the first being the Linear Static approach (LS), and the second being the Nonlinear Dynamic approach (NLD).
