Benefits of technology

[0007]The main objective of the invention is to provide a shock-absorbing tie brace having excellent capability for bearing buckling load such that it is not easily bent or buckled. The shock-absorbing tie brace has a central member and an outer frame. The central member has two ends and multiple neck portions. The neck portions are formed between the ends to form at least one enlarged portion between the neck portions. Each neck portion has a height (Hn) relative to the central line smaller than a height (He) of each one of the at least one enlarged portion, and a proportion of the height (Hc) of each neck to the height (He) of any one of the at least one enlarged portion is o.1 to 0.99. The outer frame is mounted around and encloses the central member.

Problems solved by technology

However, the conventional shock-absorbing tie brace lacks excellent capability for bearing buckling load, such that the conventional one is easily buckled or bent during an earthquake.

example

[0055]A shock-absorbing tie brace having a central member with two neck portions in the following dimension scales has been test. The whole length of the central member is 3104 millimeter (mm), the length of each neck portion is 759.27 mm, the height (Hc) of each neck portion to the central line of the central element is 23.85 mm, the length of the enlarged portion is 680 mm and the height (He) of the enlarged portion to the central line of the central element is 113, so that the proportion of the height (Hc) of each neck portion to the height (He) of the enlarged portion is 0.211. The shock-absorbing tie brace is mounted diagonally on a steel structure having beams of 4500 mm in length and columns of 3000 in length, and additional weight of approximately 6936 kg is added to the floor of the steel structure to simulate the load on the floor. The test result is shown in FIGS. 15 to 20. From the test result, the roof acceleration, roof displacement and the column shear force both in X...

Abstract

A shock-absorbing tie brace has a central member and an outer frame. The central member has two ends and multiple neck portions. The neck portions are formed between the ends to form at least one enlarged portion between the neck portions. Each neck portion has a height (Hn) relative to the central line smaller than a height (He) of each one of the at least one enlarged portion, and a proportion of the height (Hc) of each neck to the height (He) of any one of the at least one enlarged portion is o.1 to 0.99. The outer frame is mounted around and encloses the central member. Accordingly, the shock-absorbing tie brace has an excellent capability for bearing buckling load and is not easily bent or buckled.

Description

[0001]The present invention is a continuation-in-part application of the application Ser. No. 11 / 037,033, filed on Jan. 17, 2005.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a shock-absorbing tie brace, and more particularly to a shock-absorbing tie brace used in structures to absorb shock transmitted from the ground or a floor.[0004]2. Description of Related Art[0005]To enhance the strength of a structure, tie braces are mounted at an angle respectively between columns and beams supported by the columns in the structure to stiffen the frame of the structure, and shock-absorbing tie braces also absorb shocks to the structure. However, the conventional shock-absorbing tie brace lacks excellent capability for bearing buckling load, such that the conventional one is easily buckled or bent during an earthquake.[0006]To overcome the shortcomings, the present invention tends to provide a shock-absorbing tie brace to mitigate or obviate t...
