Abstract

The relationship between the static and dynamic displacements of a structure is studied and explores the application of the relationship. The key parameters are: the static stiffness of the structure, which is a measure of its resistance to an applied load; and the dynamic stiffness, which relates to a specific mode of vibration. To illustrate the salient features, two simple examples will be considered, first a beam and second a plate. These may be considered to be simple representations of a bridge and a floor respectively. The conclusions of the research are the number of modes considered increases the difference between total modal displacement and the static displacement decreases. The first mode dominated the sumof the modal displacement. It is therefore apparent that measurements of both static and dynamic stiffness can both provide useful information on the elastic behavior of a structure.

Abstract

This paper presents a study to examine the significance of longitudinal reinforcement on column strength in terms of interaction between axial capacity and bending moment. A new computer programming was developed to accelerate the computational effort. The program can be used to calculate the need of longitudinal reinforcement directly without constructing the P-M interaction diagram for a specific rectangular column with various reinforcement ratios. It can be concluded that longitudinal reinforcement ratio affects the column capacity significantly. The originality of the program is also one of the key points in the development of the program for modern analytical tool. The computational procedures developed in the program were based on ACI 318M-02 and SNI 03-2847-2002. The results have also been proven to be accurate when compared with PCA Col program.

Abstract

Construction technology has been rapidly developing nowadays which often requires the use of higher ductility of structural elements. All structural members, especially columns as primary structural components should have higher ductility so that it can delay the collapse of the buildings during earthquake. There is a significant difference in behavior between unconfined and confined concrete columns. Confined concrete columns show higher ductility compared with those unconfined. To accommodate the analysis, a computer program called MoCurv v.1.2 is developed. This program is an improvement of the earlier developed program called MoCurv v.1. This program can be used to analyze circular column sections with NSC and HSC. Five major factors are dominantly control the value of curvature ductility, i.e. transverse reinforcement spacing, number and size of longitudinal bars, strength of concrete, column size, and axial loading. Parametric study has also been done to compare the effectiveness of each parameter. It can be concluded that the most influencing parameter to the value of curvature ductility is the spacing of transverse reinforcement.

Abstract

Recently, the flood intensity that brought by tributary rivers in the catchment area of Pacal reservoir has increased, both in the quantity of runoff and sediment volume. The research aims to set up erosion rate modeling and find the formulation of the Sediment Delivery Ratio (SDR) at Pacal reservoir. The research used USLE and MUSLE methods as comparator to find sediment yield accuracy at Pacal reservoir, by applying ArcView SWAT-X software. Total average annual erosion rate in the catchment area of Pacal reservoir which has area 82 Km2 calculated using USLE and MUSLE methods are 159,31 ton/ha/yr and 582 ton/ha/yr respectively. MUSLE method resulted SDR which is most closely to SDRobservation if it is compared to USLE method. In this research, MUSLE - Sediment-Discharge Rating Curve method has evaluation values MSE = 0,08; RMSE = 0,29; and Nash = 0,75. Furthermore, Sediment Delivery Ratio at catchment area of Pacal reservoir can be formulated as 0,29 3,83. DAS Waduk Pacal SDR A with value of SDRZulis = 0,27 and sediment yield obtained from MUSLE method equal to 157,40 ton/ha/yr, while from USLE method equal to 43,09 ton/ha/yr. Evaluate sediment yield of MUSLE from SDRZulis to formulation of SDR of former researcher was value of Nash = 0,89; MAE = 0,01. Based on the research result, it is expected that the institution which has responsibility in managing the catchment area of Pacal reservoir would pay high attention to zonation map of erosion risk level and can overcome sedimentation in Pacal reservoir.

Abstract

The research is motivated rationale for reuse styrofoam waste (wrappers monitor) that is widely available on the ground that this cannot be destroyed or recycled. Utilization of waste is intended to not pollute the environment and can even be commercially valuable. In addition, this study is an attempt to find alternative materials replacement bricks. One of them is by using a mixture of portland cement, silica sand and styrofoam for the manufacture of non-structural lightweight concrete. Silica sand crushed into powder 22.44% retained on sieve no. 325 and styrofoam used in the form of small granules which pass 9.5 mm sieve. This study begins with a test mortar with silica sand content of 0%, 30%, 40%, 50% by weight of cement + silica sand. Then one of the mortar mixture composition is taken to be combined with Styrofoam to test concrete with styrofoam levels of 3%, 3.5%, 4% by weight of cement + silica sand. From the results of testing mortars, the composition of the mixture is taken as 40% silica sand and cement 60%. In testing the concrete, the greater the level of styrofoam, the smaller the volume weight, compressive strength, tensile strength and flexural strength concrete. The composition of concrete mixtures with styrofoam levels 3.5% and 4% which can be categorized as non-structural lightweight concrete material to be used as wall panels / insulation.

Abstract

A moderate M7.1 earthquake hit Canterbury on Saturday, 4 September, 2010 at 04:35:46 a.m. New Zealand time (GMT +12). It was expected to be the most damaging ground shake since the 1931 magnitude 7.8 Hawke's Bay earthquake. The epicentre was located approximately 45 km west of Christchurch, in a rural area at a depth of 10 km. There were followed by more than thousand aftershocks had been measured. An aftershock M6.3 was recorded at 12:51 pm on Tuesday, 22 February 2011. The epicentre of the aftershock was approximately 10 km south-east of the Christchurch Central Business District (CBD), near Lyttelton, at a similar depth to the initial earthquake and caused much more severe damage to CBD and residential areas nearby. Lessons learned from the Canterbury earthquake and its aftershocks are a timely reminder to Indonesian structural engineers of a number of things with respect to seismic design, construction practices and post disaster evaluation. These include: The importance of implementing the latest seismic loadings and design technology into new and existing structures without undue delay; The need to maintain effective Building Code enforcement and post-earthquake audit process, including the keeping of publicly transparent compliance records; The important role of the design engineer in observing and auditing the interpretation and implementation of the design; Vigilance to prevent improper substitution of materials and ill-considered design changes; The importance of ongoing continuing professional development and education for design, construction and building code enforcement officials. This paper also discusses the need of having a guide for conducting post-earthquake structural repairs as including a quick way to identify appropriate repair strategies.
