Abstract

ABSTRACT The most commonly encountered earthquake-resistant steel structure design in Indonesia utilizes bracing. Several commonly used earthquake-resistant steel structural systems include the Concentric Braced Frame (CBF) system. This study aims to analyze the effect of variations in the position of inverted-V CBF bracing on the structural behavior of a 6-story steel frame office building in Pontianak City. The research method involved structural modeling using ETABS 22.1 software, considering parameters such as dead load, live load, and seismic load according to SNI 1726:2019 and SNI 1727:2020. The results show that the installation of bracing significantly reduces the structure's natural period, displacement, and drift. The structural irregularity analysis indicated that all variations met the SNI 1726:2019 criteria for both horizontal and vertical irregularity. Furthermore, modal mass participation reached 100% at the 21st mode, fulfilling the requirements for dynamic analysis. The structural analysis results, particularly of the one-story bracing configuration, demonstrate its effectiveness in improving the building's seismic performance by reducing displacement and natural period. Variation 2A was assessed as the most optimal, as it provided a good structural response without requiring an excessive number of bracings. These findings can serve as a reference in the planning of earthquake-resistant structures for high-rise buildings. Keywords: Earthquake, Bracing, Displacement, Natural Period, Drift.

Abstract

Waterlogging along Cadika Road, Sintang Regency, West Kalimantan Province, indicates a problem in the urban drainage system caused by high rainfall intensity. This condition disrupts community activities, accelerates road infrastructure damage, and increases environmental risk. This study aims to analyze the design flood discharge, evaluate the capacity of the existing drainage channel, and redesign the channel dimensions so that it can effectively convey surface runoff. A quantitative descriptive approach was used, combining primary data from field observation of inundation and channel conditions with secondary data consisting of ten years (2016–2025) of daily maximum rainfall from the BMKG Tebelian Sintang station. Hydrological analysis was carried out using three frequency-distribution methods—Normal, Log Pearson Type III, and Gumbel—tested for goodness of fit using the Chi-Square and Smirnov-Kolmogorov tests. The Gumbel distribution was selected as the primary reference because its statistical parameters satisfied the theoretical criteria for extreme data, with a coefficient of variation (Cv) of 0.195, a coefficient of skewness (Cs) of 1.035 (≤ 1.139), and a coefficient of kurtosis (Ck) of 5.008 (≤ 5.400). Design flood discharge was calculated with the Rational Method, while channel capacity was analyzed using Manning's equation. Results show that the existing channel capacity cannot accommodate the design flood discharge for any return period. On the left side, the existing capacity is only 0.6932 m³/s, while the design flood discharges for the 2-, 5-, and 10-year return periods are 2.564, 3.177, and 3.582 m³/s, respectively; a similar deficit occurs on the right side. The channel dimensions were therefore redesigned to a width of 1.10 m and a depth of 1.20 m for both sides, increasing the capacity to 3.613 m³/s, which is sufficient to accommodate all design flood discharges (Qs > Qr).
