Reduced forest products cause also reduced of large-dimensional wood that has high quality. One alternative to solve the problem is by doing laminate engineering by combining different quality wooden layers into specific sized beams as desired. The type of wood and the position of layer give effect to the laminate beam capacity. The aim of this research was to find out the flexural capacity (MOR) of Mahang and Meranti wood laminated beams which layers were varied which then the result of the laminated beam was compared with the solid beams. There were 3 types of laminate specimens made with dimension 5x7x76 cm3 which consisted of 7 layers; BL K1 beam consisted of 2 layers of Meranti wood at the top and bottom of the beam and 5 layers of Mahang in the middle; BL K2 beam consisted of 4 layers of Meranti wood at the top and bottom of the beam, and 3 layers of Mahang in the middle; and BL K3 beam consisted of 6 layers of Meranti wood at the top and bottom of the beam and 1 layer of Mahang in the middle. The test results showed that the use of wood of higher specific gravity at the outermost layer has increased the flexural capacity (MOR) and modulus of elasticity (MOE), particularly in laminated beams (Meranti wood and Mahang wood) with the same numbers of layers. Moreover, in same number or greater layer proportion between Mahang and Meranti wood, the result showed the increased of MOR and MOE of laminated beams compared with solid beam that has low specific gravity (Mahang).

The City of Banjarmasin has very low soil bearing capacity leading to a significant number of buildings experiencing foundation settlement. This causes many elements of the buildings to develop cracks and to lean. The foundation settlement is modelled using ANSYS by taking five building structure models with brick walls loaded with their selves weight. Through this modelling the crack pattern and the stress distribution on both walls and the structural elements can be visualised and identified. The results show that the following columns experiencing foundation settlement develop longitudinal cracks, crack patterns on brick walls are diagonal at every bottom corner of the columns and vertical at the edge of the inner columns if there is no foundation settlement. Crack patterns on brick walls take form of a letter V if only one or two outer column experience foundation settlement, and crack patterns on brick walls also take form of an inverted letter V if only the inner columns or two adjacent columns experience foundation settlement. Foundation settlement experienced by inner columns of a brick wall is a major cause of damage to structural components.
