Abstract

Earthquake-resistant structures using dampers have begun to be implemented in Indonesia. Structures equipped with dampers can reduce plastic deformation in primary structural elements, inter-story drift, and floor acceleration. According to SNI 1726:2019 Article 13, the seismic design analysis of structures with damping systems may employ nonlinear time history analysis (NLTHA) or alternative procedures such as response spectrum analysis (RSA) and equivalent lateral force (ELF). However, NLTHA is computationally inefficient and requires considerably longer processing time compared to alternative procedures. The RSA procedure also stipulates that dampers may be used solely to satisfy inter-story drift requirements per SNI 1726:2019, so that bare frame structures can be analysed conventionally to meet the strength requirements of SNI 2847:2019. The novelty of this research lies in applying the RSA method as a computationally efficient alternative to NLTHA for the analysis and design of structures with viscoelastic dampers (VED), which is not yet widely practiced by engineers in Indonesia. In this study, the structure was modelled with VED and analysed using RSA through iterative stages: viscous damping iteration (βvm), iteration at the DBE earthquake level to satisfy the minimum base shear V and βmd ≤ 35%, and iteration at the MCER earthquake level to satisfy story drift and story displacement limits. Using the RSA method, 12 dampers per direction (24 per floor) were installed, satisfying the RSA minimum requirement of 2 dampers per direction and 4 dampers per floor. Based on the analysis, the minimum base shear (Vmin) was 0.9085V. It is concluded that the alternative RSA procedure can be applied and satisfies the requirements of SNI 1726:2019 for damping systems.

Abstract

The use of non-prismatic gable frame steel structures is common in industrial buildings due to their structural efficiency. However, their performance depends significantly on the quality of the steel material. This study evaluates the mechanical properties of Chinese structural steel grade Q355B (GB/T 1591-2018) and assesses its structural performance in a non-prismatic gable frame system at PT Unimotor Technology Indonesia. A quantitative approach was employed through laboratory testing using the Brinell and Rebound methods to determine steel hardness and ultimate tensile strength (Fu). The test results showed a minimum Fu value of 495 MPa. Nevertheless, conservative design properties specified for Q355B steel (Fy = 355 MPa and Fu = 470 MPa) were adopted in the structural analysis. A three-dimensional model was developed using CSI ETABS V.21.0 to represent the non-prismatic gable frame geometry. Structural analysis was conducted in accordance with SNI 1727:2020, SNI 1726:2019, and LRFD load combinations, considering dead, live, wind, and seismic loads. The results indicate that all structural members satisfy the required strength criteria. The maximum flexural–shear interaction ratio was 0.601, while the flexural–compression interaction ratio was 0.57, both below the allowable limit of 1.0. The structure also met the requirements for lateral-torsional buckling resistance. Based on the analysis, the non-prismatic gable frame system using Q355B steel is structurally safe and complies with the requirements of SNI 1729:2020.

Abstract

The effectiveness of road infrastructure development depends heavily on procurement quality through electronic tendering mechanisms. Within the Electronic Procurement Service (LPSE) system, competition intensity and bidding efficiency are theoretically the primary determinants of tender outcome quality. However, no empirical study has specifically examined both factors in regional construction markets with unique geographical characteristics such as Banjarmasin City. This study aims to analyze the effect of competition intensity and bidding efficiency on road project tender outcomes in the Banjarmasin City LPSE for the period 2016–2023, both partially and simultaneously. A sample of 30 work packages was selected through purposive sampling from the Banjarmasin City LPSE portal. Analysis was conducted using multiple linear regression with a robust standard errors approach. The results indicate that competition intensity has a positive and significant effect (α = 10%), while bidding efficiency has a negative and significant effect (α = 5%) on tender outcomes. Simultaneously, both variables significantly influence tender outcomes with a coefficient of determination of 19.66%. These findings suggest that tender outcomes are not solely determined by the number of participants and price rationality, highlighting the need for a more comprehensive procurement approach in evaluating tender competition quality at the regional level.
