Skop kajian ini adalah tertumpu kepada kesan daripada lokasi tangki
simpanan air hujan ke atas kestabilan bangunan tinggi. Satu bangunan tinggi sedia
ada di kawasan bandar telah dipilih. Bangunan tinggi tersebut adalah 77.0 m
tinggi dan 59.35 m panjang dan 22.75 m lebar. Beban angin yang dikenakan pada
bangunan tinggi tersebut dikira dengan merujuk kepada MS 1553:2002. Supply
Side Approach telah digunakan untuk menentukan saiz tangki simpanan air hujan.
Bangunan tinggi tersebut dimodelkan dan dianalisiskan dengan menggunakan
perisian komputer – EsteemPlus 6.2.
Daripada projek ini, didapati pesongan maksimum untuk sebuah bangunan
tinggi akan berubah dengan orientasi perletakan tangki simpanan air hujan.
Keputusan menunjukkan bahawa impak perletakan tangki simpanan air hujan
dapat dikurangkan jika ia diletakkan berhampiran dengan pusat tengah bangunan
tersebut. Walau bagaimanapun, analisis perlu dilakukan ke atas sesuatu bangunan
sebelum tangki simpanan air hujan dipasang.

The scope of this study is focussed on the effect of different rooftop
rainwater harvesting storage orientations on the structural stability of a high rise
building. An existing high rise building in urban area is selected. The high rise
building is 77.0 m in height and 59.35 m x 22.75 m in plan. The wind load on the
high rise building is calculated by referring to MS 1553:2002. Supply Side
Approach is used to size the storage tanks. The high rise building is modelled and
analysed by computer software – EsteemPlus 6.2.
From this project, it is found that the deflection of the high rise building
varies with the orientation of the RRWH storage tank installation. The results also
show that rainwater harvesting storage tank installation in high rise building is
likely to reduce the impact of wind action if the storage tank is placed near to the
centre of the building. However, it is essential to analyse the behaviour of a
building before installing any rainwater harvesting storage tank.
