4.2 STRUCTURAL SYSTEMS

4.2.1 INTRODUCTION

This design basis report lists the general design criteria that will be used in the calculations for the design of structural items involved in this task. This design criterion complies with all relevant Royal Commission codes and standards, latest editions of engineering and industry codes and Saudi Arabian government codes.

The function and occupancy of the different buildings is divided into three major categories,

(A) Jubail Governor’s Office. (B) Dawa office. (C) Patrol Police Office.

Each of the buildings is well described in the Architectural section of this DBR.

4.2.2 STRUCTURAL SYSTEM

4.2.2.1 Sub-Structure

For all of buildings mentioned above; Soil bearing pressure and other subsurface information for use in foundation design shall be in accordance with the recommendations of the geotechnical investigation report. However due to unavailability of the geotechnical report at this current design stage, the

of 98


foundation is designed for assumed bearing capacity of 100 KN/m2. The proposed foundation system is as follows:

For most of the building area the foundation system is spread footings, but at some locations combined footings are proposed to avoid overlapping OR any closely spaced isolated footings. For more details refer to the structural drawings.

The assumed minimum foundation embedment depth is 1.375 m below the bottom of slab on grade.

Reinforced concrete grade beams are applied at the building perimeter in order to carry the exterior composite CMU walls. Interior grade beams will only be provided where it is deemed necessary to increase the strength of the structure. Interior CMU walls shall be supported by the thickened slab on grade.

Reinforced concrete slabs-on-grade is applied. The slabs-on-grade are non-structural and mildly reinforced with welded wire fabric.

The atmosphere, soil, and water conditions in Jubail Town are severely corrosive. The construction of foundations and superstructures include competent corrosion mitigation measures to achieve long-term durability. At this design stage, Coal tar epoxy coating will be applied to all the structural concrete elements below finished grade.

For more details of the proposed sub-structure system, refer to the attached SE drawings with this design stage package.

4.2.2.2 Civil-Structural works

For any of the Structural works outside the main building (likewise manholes, foundation of the electrical poles, retaining walls, etc), concept is presented in our civil drawings.

4.2.2.3 Super-Structure

At this current design stage various framing systems of the buildings are proposed and recommended for the review and approval. The proposals are intended to finalize the best possible framing system.

A. Jubail Governor’s Office : The following two options are presented for the structural system of the ground + one storey building.

Option 1: Hollow Core Slabs having a thickness in the range of 150 mm to 250 mm are proposed to be supported by reinforced concrete beam-column frames having span bays at intervals in the range of 6.0 m to 12.0 m; however a long span reinforced concrete dome is proposed above roof level.

Option 2: Reinforced concrete solid beam-slab frame supported on columns is proposed in this option, the building floor forms simple two way and one way panels. One way solid joist frame is proposed to achieve longer spans of 12.0 m length, in the areas such as the meeting room.

of 98


Option 3: Considering the occupancy and architectural features of the building a Steel framing system is not feasible for this type of building.

Recommendation: Hollow core slab system (Option1) is recommended here, considering the large slab spans with lesser dead weight and time saving in construction.

B. Dawa Office : Following two options are presented for the structural system of this ground + one storey building.

Option 1: Hollow core slabs having a thickness in the range of 150 mm to 250 mm are proposed to be supported by reinforced concrete beam-column frames having span bays at intervals in the range of 6.0 m to 12.0 m, However a long span reinforced concrete dome is proposed above roof level.

Option 2: Reinforced concrete solid beam-slab frame supported on columns is proposed in this option, the building floor forms simple two way and one way panels. One way solid joist frame is proposed to achieve longer spans of 12.0 m length, in the areas like meeting rooms.

Option3: Considering the occupancy and architectural features of the building steel framing system is not feasible for this type of building.

Recommendation: Hollow core slab system (Option1) is recommended here, considering the large slab spans with lesser dead weight and time saving in construction.

C. Patrol Police Station: As the building is a site adaptation from (027-T20, Task No. 1, Contract 611-C27), therefore a similar framing system of reinforced concrete flat plat is being adapted in this task.

Systems Components Description:

Water Supply: Fire Water System is to be tied-in to the Potable/Fire water loop around the building. Refer to civil site plans for fire and potable water drawings.

of 98


Systems Operational Philosophy & Controls Description:

A- General.

A typical fire suppression water sprinkler system as installed in many buildings includes an array of individual fire sprinklers which are supplied with water through a main conduit and various branch conduits.

B- Operation.

The individual fire sprinklers are generally provided with a fusable link that melts when the ambient temperature reaches a predetermined level indicative of a fire.The melting of the member opens the fire sprinkler to spray water in order tosuppress the fire. Water damage is minimized: The individual fire sprinklers are provided with afusable link to be melt so that the spray of water will hopefully be limited to theregion of the building where the fire is present. In this way, the extent of waterdamage may be minimized.

B-1 alarm.

Such fire suppression systems also oftentimes have one or more alarms thatdetects the flow of water through the main conduit and to indicate that a fire has started. The alarm typically triggers an audible signal to warn occupants of the building that a fire has started and may also send an appropriate signal directly to fire department.

B-1-1 minimum water flow required to trigger alarm.

A flow of water, even from a single sprinkler is sufficient to move the member and trigger the alarm. Oftentimes, such water flow indicator alarms are electrically connected to an audible alarm single generator as well as to light panels to indicate the area in which the fire has occurred.

B-2 The community water supply system.

Fire suppression systems which include water sprinklers are oftentimes in fluid communication with the community water supply system or with whatever source of potable water is available in the vicinity. The water within the fire suppression system itself, however, can remain within the piping for a considerable period of time and is considered to be stagnant water.Note that water supply line to the building is provided by back flow preventer, Refer to civil site drawings for fire and potable water drawing.

B-3 The fire department.

In addition, a pump provided by the fire department will be connected to an inlet in communication with the fire suppression system in order to provide additional water and/or pressure in the event of a fire.
